chore: pre-release v0.2.1-dev

* feat/upload-bar: add a upload bar when user upload file, indicate the upload process

* feat/save-loading-status: add save status when click back button from editor

* fix: address PR review issues in upload and save features

- Replace deprecated substr() with substring() in UploadContext
- Fix broken error handling that checked stale task status
- Fix missing useEffect dependency in UploadStatus
- Fix CSS class conflict in progress bar styling
- Add error recovery for save state in Editor (reset on failure)
- Use .finally() instead of .then() to ensure refresh on upload failure
- Fix inconsistent indentation in UploadContext

* fix e2e tests

-# 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.

 When running ExcaliDash behind Traefik, Nginx, or another reverse proxy, configure both containers so that API + WebSocket calls resolve correctly:
 
-- `FRONTEND_URL` (backend) must match the public URL that users hit (e.g. `https://excalidash.example.com`). This controls CORS and Socket.IO origin checks. **Supports multiple comma-separated URLs** for accessing from different addresses.
-- `TRUST_PROXY` (backend) should be set to `1` when requests pass through one trusted reverse proxy hop (for example: frontend nginx -> backend) and forwarded headers are sanitized. This ensures rate limiting and logging use the real client IP from trusted proxy headers.

 Without this, each container generates its own ephemeral CSRF secret, causing token validation failures when requests are routed to different replicas. Single-container deployments work without this setting.
 
-### Authentication Modes (Local + OIDC)
-
-ExcaliDash supports three auth modes via backend `AUTH_MODE`:
-
-- `local` (default): native email/password login only.
-- `hybrid`: native login + OIDC login.
-- `oidc_enforced`: OIDC-only login (native login/register disabled).

-In `oidc_enforced` mode, unauthenticated users are automatically redirected to `/api/auth/oidc/start`.

-To simulate first-run authentication choice flows in local development:

-```bash
-cd ExcaliDash/backend
-
-# Preview what would change (no data modifications)
-npm run dev:simulate-auth-onboarding:dry-run
-
-# Simulate "fresh install" onboarding state
-# (wipes drawings/collections/libraries and removes non-bootstrap users)
-npm run dev:simulate-auth-onboarding:fresh

-# Simulate "migration" onboarding state (ensures legacy data exists)
-npm run dev:simulate-auth-onboarding:migration

-After running a simulation while the backend is already running, wait about 5 seconds
