Add security hardening: input validation, CSP headers, backup rotation, error handling

- Add collection name validation and sanitization (POST/PUT) - Add library items count and size limits - Add UUID/safe ID validation for route parameters - Add Socket.io event input validation and sanitization - Tighten CSP with base-uri, form-action directives and HSTS header - Add timestamped backup rotation (keep 5 most recent) for db import - Add path traversal protection for file uploads and archive names - Add global error handler to prevent stack trace leakage - Add 21 new security tests Co-authored-by: ZimengXiong <83783148+ZimengXiong@users.noreply.github.com>

-# Fork Summary
-
-This fork adds optional security features and UX improvements with **zero breaking changes** and **minimal migration overhead**. All security features are **disabled by default** via feature flags.
-
-## Security Features Added
-
-1. **Password Reset** - Token-based password reset flow (`/auth/password-reset-request`, `/auth/password-reset-confirm`)
-2. **Refresh Token Rotation** - Prevents token reuse by rotating refresh tokens on each use
-3. **Audit Logging** - Logs security events (logins, password changes, deletions) for compliance
-
-## UX Improvements Added
-
-1. **Profile Page** - View and edit personal information, change password (`/profile`)
-2. **Select All Button** - Quick selection of all drawings in current view
-3. **Sort Dropdown** - Improved sort controls with icons and separate direction toggle
-4. **Auto-hide Header** - Editor header auto-hides to maximize drawing space (with toggle)
-
-## Backward Compatibility
-
-✅ All security features disabled by default  
-✅ No breaking changes to existing code  
-✅ Graceful degradation (missing tables don't cause errors)  
-✅ Optional database migration  
-
-## Enable Security Features
-
-Set in `backend/.env`:
-```bash
-ENABLE_PASSWORD_RESET=true
-ENABLE_REFRESH_TOKEN_ROTATION=true
-ENABLE_AUDIT_LOGGING=true
-```
-
-Then run migration:
-```bash
-cd backend && npx prisma migrate deploy
-```
-
-## Migration Strategy
-
-**For base project:** Keep features disabled (default) - no migration needed, zero risk.
-
-**For this fork:** Enable features via environment variables when ready.
-
-## Database Changes
-
-Migration adds 3 optional tables (only used when features enabled):
- `PasswordResetToken` - For password reset flow
- `RefreshToken` - For token rotation tracking
- `AuditLog` - For security event logging
-
-## Code Changes
-
-### Backend
- Feature flags in `backend/src/config.ts`
- Conditional logic in auth endpoints
- Graceful error handling for missing tables
- New endpoints: `/auth/profile` (PUT), `/auth/change-password` (POST)
- Audit logging utility (`backend/src/utils/audit.ts`)
-
-### Frontend
- Password reset pages (`/reset-password`, `/reset-password-confirm`)
- Profile page (`/profile`)
- Select All button in Dashboard
- Sort dropdown with icons
- Auto-hide header in Editor with toggle
- Updated API client for token rotation
-
-All changes are backward compatible and optional.

-Multi user setup is opt-in, single user by default
+CSRF Protection (8a78b2b)

-Multi-user support for excalidash
- Admin dashboard
- Password reset, force user password reset (admin only), account lockout recovery
- Rate limits
+  - Implemented comprehensive CSRF (Cross-Site Request Forgery) protection for enhanced security
+  - Added new backend/src/security.ts module for security utilities
+  - Frontend API layer now handles CSRF tokens automatically
+  - Added integration tests for CSRF validation

-Deprecates .json and .sqlite database backups in favor of .excalidash archives (user scoped, prevents exporting of senstive information). Legacy import is maintained.
+  Upload Progress Indicator (8f9b9b4)

+  - Added a visual upload progress bar when users upload files
+  - New UploadContext for managing upload state across components
+  - New UploadStatus component displaying real-time upload progress
+  - Save status indicator when navigating back from the editor
+  - Improved error handling and recovery for failed uploads
+
+  Bug Fixes
+
+  - Fixed broken e2e tests (cae8f3c)
+  - Replaced deprecated substr() with substring()
+  - Fixed stale state issues in error handling
+  - Fixed missing useEffect dependencies
+  - Fixed CSS class conflicts in progress bar styling
+  - Added error recovery for save state in Editor
+
+  Infrastructure
+
+  - Updated docker-compose configurations with new environment variables
+  - E2E test suite improvements and reliability fixes
+  - Added Kubernetes deployment note in README
+
+### Kubernetes
+
+  A `CSRF_SECRET` environment variable is now required for CSRF protection. Generate a secure 32+ character random string:
+
+  ```bash
+  openssl rand -base64 32
+
+  Add it to your deployment:
+  - Docker Compose: Add CSRF_SECRET=<your-secret> to the backend service environment
+  - Kubernetes: Add to your ConfigMap/Secret and reference in the backend deployment
+
+  If not set, the backend will refuse to start.
+  ```
