chore: bump version to 1.0.74 (backend + frontend)

- Remove completed PRODUCTION_TODO_LIST.md
- Consolidate deployment guides: keep comprehensive PRODUCTION_DEPLOYMENT_GUIDE.md, remove redundant PRODUCTION_DEPLOYMENT.md
- Update all .env.example files to reflect current system:
  - Remove deprecated ADMIN_EMAIL/ADMIN_PASSWORD (now auto-generated)
  - Add proper documentation for all environment variables
  - Clarify that Umami config is optional (primary via Admin UI)
  - Add realistic examples for SMTP providers
  - Update ports to match actual defaults (3001)
- Update PRODUCTION_DEPLOYMENT_GUIDE.md:
  - Document auto-generated admin credentials process
  - Add Traefik configuration section
  - Update security checklist with current features
  - Fix outdated environment variables
  - Add nginx proxy configuration details

 5. **Frontend Status**: Only skeleton exists - requires full implementation based on PRD
 6. **Umami Analytics**: Track password entries, downloads, views, expiration warnings
 
+## Troubleshooting Guidelines
+
+### Before ANY Production Troubleshooting:
+1. **ALWAYS request specific details**:
+   - Production server URL/IP
+   - Current error messages/logs
+   - Recent changes or deployments
+   - Affected users/galleries
+   - Time of issue occurrence
+
+2. **Thorough Analysis Required**:
+   - Use detailed thinking/analysis for EVERY troubleshooting task
+   - Review all related code before suggesting changes
+   - Consider all potential side effects
+   - Never make assumptions about production environment
+
+3. **Safe Troubleshooting Steps**:
+   - First, reproduce issue in local/dev environment
+   - Analyze logs without modifying production
+   - Create detailed action plan before any changes
+   - Always have rollback strategy ready
+   - Document every step taken
+
+### Common Issues & Safe Approaches:
+- **Email not sending**: Check email_queue table, SMTP settings, service status
+- **Photos not loading**: Verify file permissions, storage paths, nginx config
+- **Gallery access issues**: Check JWT tokens, expiration dates, access_logs
+- **Performance problems**: Analyze with monitoring tools first, never experiment
+
+### Data Safety Rules:
+- NEVER delete or modify production data without explicit backup confirmation
+- ALWAYS verify backups exist before any data operations
+- NO direct database modifications without transaction safety
+- Log all actions for audit trail

+## Documentation & Development Practices
+
+### Documentation Guidelines:
+- **NEVER create new documentation files for simple tasks**
+- **ALWAYS update existing documentation (like this CLAUDE.md)**
+- Only create new .md files when explicitly requested
+- Avoid creating temporary scripts for one-off tasks
+
+### Development Best Practices:
+- Test all changes thoroughly in local environment first
+- Use version control for all changes
+- Keep commits atomic and well-described
+- Review impact on all integrated services
+- Consider backward compatibility
+- Update tests when changing functionality
+
+### Production Deployment Checklist:
+- [ ] All tests passing locally
+- [ ] Linting and type checks pass
+- [ ] Database migrations tested with rollback plan
+- [ ] Environment variables documented
+- [ ] Backup strategy confirmed
+- [ ] Monitoring alerts configured
+- [ ] Rollback procedure documented
+- [ ] Stakeholders notified of maintenance window

-# Production Deployment Guide
-
-This guide explains how to deploy PicPeak in production behind a reverse proxy like Traefik.
-
-## Environment Configuration
-
-### Frontend Configuration
-
-For production deployment behind a reverse proxy (Traefik, Nginx, etc.), the frontend should use relative URLs to automatically inherit the protocol (HTTPS) and domain.
-
-1. Copy the production environment template:
-   ```bash
-   cp frontend/.env.production.example frontend/.env.production
-   ```
-
-2. Set the API URL to use relative path:
-   ```env
-   # frontend/.env.production
-   VITE_API_URL=/api
-   ```
-
-   This ensures all API calls will use the same domain and protocol as the frontend.
-
-### Backend Configuration
-
-Ensure your backend `.env` file has the correct URLs:
-```env
-# backend/.env
-FRONTEND_URL=https://yourdomain.com
-ADMIN_URL=https://yourdomain.com
-```
-
-## Docker Compose Production
-
-When using Docker Compose in production:
-
-1. Build with production environment:
-   ```bash
-   docker-compose -f docker-compose.prod.yml build --build-arg NODE_ENV=production
-   ```
-
-2. The frontend nginx configuration already includes proper proxy settings for:
-   - `/api` → Backend API
-   - `/photos` → Protected photo access
-   - `/thumbnails` → Thumbnail images
-   - `/uploads` → Public uploads (logos, favicons)
-
-## Traefik Configuration
-
-Example Traefik labels for docker-compose:
-
-```yaml
-services:
-  frontend:
-    labels:
-      - "traefik.enable=true"
-      - "traefik.http.routers.picpeak.rule=Host(`yourdomain.com`)"
-      - "traefik.http.routers.picpeak.entrypoints=websecure"
-      - "traefik.http.routers.picpeak.tls.certresolver=letsencrypt"
-      - "traefik.http.services.picpeak.loadbalancer.server.port=80"
-```
-
-## Important Notes
-
-1. **No Hardcoded URLs**: The application uses environment variables with relative URL fallbacks, making it production-ready.
-
-2. **HTTPS Only**: When `VITE_API_URL=/api`, all requests will use the same protocol as the page (HTTPS in production).
-
-3. **CORS Configuration**: The backend CORS is configured to accept requests from the URLs specified in `FRONTEND_URL` and `ADMIN_URL`.
-
-4. **Static Assets**: All static assets (photos, thumbnails, uploads) are served through the nginx proxy, inheriting authentication headers.
-
-## Verification
-
-After deployment, verify:
-
-1. Check browser console for any localhost URLs (there should be none)
-2. Verify all API calls use HTTPS
-3. Check that images load correctly with authentication
-4. Test favicon and logo display
-
-## Troubleshooting
-
-If you see console errors about localhost:
-
-1. Ensure `VITE_API_URL=/api` in frontend environment
-2. Clear browser cache
-3. Rebuild frontend with production environment:
-   ```bash
-   cd frontend
-   npm run build
-   ```
-
-If images don't load:
-
-1. Check that nginx proxy locations are configured
-2. Verify authentication tokens are being sent
-3. Check backend logs for authentication errors

+
+### Frontend Environment
+```bash
+# frontend/.env.production
+VITE_API_URL=/api  # Uses relative path for reverse proxy

+# Security Logging Documentation
+
+## Overview
+This document describes the comprehensive security logging implemented in the PicPeak application to track authentication failures, rate limiting, and suspicious activities.
+
+## Log Files
+
+### 1. **security.log**
+- Location: `logs/security.log`
+- Contains: All security-related events (authentication, rate limiting, suspicious activity)
+- Max Size: 20MB with rotation (keeps 10 files)
+- Format: JSON with timestamp
+
+### 2. **error.log**
+- Location: `logs/error.log`
+- Contains: All error-level logs including auth failures
+- Max Size: 10MB with rotation (keeps 5 files)
+
+### 3. **combined.log**
+- Location: `logs/combined.log`
+- Contains: All logs (info, warn, error)
+- Max Size: 50MB with rotation (keeps 10 files)
+
+## Security Events Logged
+
+### Rate Limiting
+When rate limits are exceeded, the following is logged:
+```json
+{
+  "timestamp": "2024-01-18 14:23:45.123",
+  "level": "warn",
+  "message": "Rate limit exceeded",
+  "security": true,
+  "ip": "192.168.1.1",
+  "path": "/api/admin/login",
+  "method": "POST",
+  "authenticated": false,
+  "userAgent": "Mozilla/5.0...",
+  "referer": "https://app.example.com",
+  "origin": "https://app.example.com",
+  "headers": {
+    "x-forwarded-for": "192.168.1.1",
+    "x-real-ip": "192.168.1.1"
+  },
+  "requestUrl": "/api/admin/login",
+  "rateLimitInfo": {
+    "limit": 5,
+    "current": 6,
+    "remaining": 0,
+    "resetTime": "2024-01-18T14:38:45.123Z"
+  }
+}
+```
+
+### Authentication Failures
+
+#### Admin Login Failures
+- Tracked in `login_attempts` table
+- Logged with: IP address, username, user agent, timestamp
+- Account lockout after 5 failures in 15 minutes
+
+#### Gallery Password Failures
+- Tracked in `access_logs` table with action='login_fail'
+- Logged with: event_id, IP address, user agent
+- Gallery lockout after 5 failures in 15 minutes
+
+### JWT Validation Failures
+```json
+{
+  "timestamp": "2024-01-18 14:23:45.123",
+  "level": "warn",
+  "message": "JWT validation failed",
+  "ip": "192.168.1.1",
+  "path": "/api/admin/events",
+  "method": "GET",
+  "userAgent": "Mozilla/5.0...",
+  "error": "TokenExpiredError",
+  "message": "jwt expired"
+}
+```
+
+### Suspicious Activity
+- Multiple IPs attempting login for same account
+- Token usage from different IP than issued
+- Token usage after password change
+- Revoked token usage attempts
+
+## Configuration Settings
+
+All rate limiting settings are configurable via the admin panel:
+
+| Setting | Default | Range | Description |
+|---------|---------|-------|-------------|
+| rate_limit_enabled | true | - | Enable/disable rate limiting |
+| rate_limit_window_minutes | 15 | 1-60 | Time window for rate limit |
+| rate_limit_max_requests | 1000 | 10-10000 | Max requests for general endpoints |
+| rate_limit_auth_max_requests | 5 | 1-100 | Max requests for auth endpoints |
+| rate_limit_skip_authenticated | true | - | Skip rate limit for authenticated requests |
+| rate_limit_public_endpoints_only | false | - | Only rate limit public endpoints |
+
+## Database Tables
+
+### login_attempts
+```sql
+- id
+- username
+- ip_address
+- user_agent
+- success (boolean)
+- created_at
+```
+
+### access_logs
+```sql
+- id
+- event_id
+- ip_address
+- user_agent
+- action ('view', 'download', 'login_success', 'login_fail')
+- photo_id (nullable)
+- created_at
+```
+
+## Environment Variables
+
+- `LOG_LEVEL`: Set logging level (default: 'info')
+- `LOG_TO_CONSOLE`: Enable console logging in production (default: false)
+
+## Monitoring Recommendations
+
+1. **Set up alerts for:**
+   - Rate limit exceeded events (possible DDoS)
+   - Multiple failed login attempts from same IP
+   - Account lockout events
+   - JWT validation failures spike
+
+2. **Regular review:**
+   - Check security.log for patterns
+   - Review login_attempts table for brute force attempts
+   - Monitor access_logs for suspicious gallery access patterns
+
+3. **Log analysis tools:**
+   - Use log aggregation tools (ELK stack, Splunk)
+   - Set up dashboards for security metrics
+   - Configure alerts for threshold breaches
+
+## Production Deployment Notes
+
+1. Ensure logs directory has proper permissions
+2. Set up log rotation outside of application if needed
+3. Consider shipping logs to centralized logging service
+4. Monitor disk space for log files
+5. Set `LOG_TO_CONSOLE=true` for container deployments
+
+## Security Best Practices
+
+1. Never log sensitive data (passwords, tokens)
+2. Use generic error messages to prevent user enumeration
+3. Clean up old login attempts regularly (7 days retention)
+4. Monitor for unusual patterns in real-time
+5. Keep rate limit settings appropriate for your usage

+# Nginx Configuration Fix for Photo Authentication
+
+If photos and thumbnails are not loading in gallery view but work in admin, it's likely that the Authorization header is being stripped by nginx or another reverse proxy.
+
+## Common Issue
+
+The `Authorization` header is often not passed through by default in nginx proxy configurations.
+
+## Fix
+
+Add these lines to your nginx configuration for the PicPeak location block:
+
+```nginx
+location / {
+    proxy_pass http://localhost:3001;
+    
+    # Important: Pass the Authorization header
+    proxy_pass_header Authorization;
+    proxy_set_header Authorization $http_authorization;
+    
+    # Other standard proxy headers
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+}
+```
+
+## Alternative Fix Using Traefik
+
+If using Traefik, ensure headers are passed:
+
+```yaml
+services:
+  picpeak:
+    labels:
+      - "traefik.http.middlewares.picpeak-headers.headers.customrequestheaders.Authorization="
+```
+
+## Testing
+
+1. Check if Authorization header is reaching the backend:
+   ```bash
+   curl -H "Authorization: Bearer YOUR_TOKEN" https://picpeak.yourdomain.com/thumbnails/test.jpg -v
+   ```
+
+2. Check nginx logs to see if the header is present:
+   ```bash
+   tail -f /var/log/nginx/access.log
+   ```
+
+## Docker Compose Fix
+
+If using docker-compose with nginx proxy, add:
+
+```yaml
+environment:
+  - NGINX_PROXY_PASS_HEADER=Authorization
+```
