feat: add storage management scripts for production troubleshooting

- Add check-storage.js to verify storage structure and file existence
- Add regenerate-thumbnails.js to recreate missing thumbnail files
- Include comprehensive README with usage instructions
- Scripts help diagnose and fix missing photo/thumbnail issues

These scripts are essential for production maintenance when photos
or thumbnails are missing from the storage directory.

+# Storage Management Scripts
+
+## check-storage.js
+
+Checks the storage directory structure and verifies that photo files exist.
+
+### Usage:
+```bash
+# Check overall storage structure
+node scripts/check-storage.js
+
+# Check specific event
+node scripts/check-storage.js wedding-test-gallery-2025-07-14-1
+```
+
+### What it checks:
+- Storage directory structure and permissions
+- Event directories
+- Photo files existence
+- Thumbnail files existence
+- Database vs filesystem consistency
+
+## regenerate-thumbnails.js
+
+Regenerates missing thumbnails for photos in the database.
+
+### Usage:
+```bash
+# Regenerate all missing thumbnails
+node scripts/regenerate-thumbnails.js
+
+# Regenerate thumbnails for specific event (by ID)
+node scripts/regenerate-thumbnails.js 2
+```
+
+### What it does:
+- Scans photos in database
+- Checks if thumbnails exist
+- Generates missing thumbnails using Sharp
+- Updates database with thumbnail paths
+- Reports success/error statistics
+
+### Prerequisites:
+- Node.js environment
+- Database access
+- Write permissions to storage directory
+- Sharp library installed
+
+## Production Usage
+
+On your production server:
+
+1. First, check the storage structure:
+   ```bash
+   cd /path/to/picpeak/backend
+   NODE_ENV=production node scripts/check-storage.js wedding-test-gallery-2025-07-14-1
+   ```
+
+2. If thumbnails are missing, regenerate them:
+   ```bash
+   NODE_ENV=production node scripts/regenerate-thumbnails.js 2
+   ```
+
+Note: Replace `2` with the actual event ID from your database.
