chore: bump version to 1.0.65 (backend + frontend)

- Add comprehensive logging for rate limit blocks with full request details
  - IP address (with proper proxy detection), user agent, headers, timestamps
  - Rate limit info (current count, limit, remaining, reset time)
  - Separate tracking for auth vs general endpoints

- Enhance authentication failure logging
  - JWT validation failures with detailed error info
  - Admin auth attempts without token
  - Failed token validation with user context
  - All events include IP, path, method, user agent

- Improve Winston logger configuration for production
  - Add automatic log rotation (10MB errors, 50MB combined)
  - Create separate security.log for auth/rate limit events
  - Ensure logs directory exists automatically
  - Add structured JSON format for log aggregation
  - Support container logging with LOG_TO_CONSOLE env var

- Create comprehensive documentation
  - Security logging guide with examples
  - Monitoring recommendations
  - Configuration reference

- Add test script to verify logging functionality

All rate limit settings remain configurable via admin panel:
- Window duration, max requests, auth limits
- Skip authenticated requests option
- Public endpoints only option

+# 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
