fix: load configuration from config.json and fix authentication

- Load anime_directory and master_password_hash from config.json on startup
- Sync configuration from config.json to settings object in fastapi_app.py
- Update dependencies.py to load config from JSON if not in environment
- Fix app.js to use makeAuthenticatedRequest() for all authenticated API calls
- Fix API endpoint paths from /api/v1/anime to /api/anime
- Update auth_service.py to load master_password_hash from config.json
- Update auth.py setup endpoint to save master_password_hash to config
- Fix rate limiting code to satisfy type checker
- Update config.json with test master password hash

Fixes:
- 401 Unauthorized errors on /api/anime endpoint
- 503 Service Unavailable errors on /api/anime/process/locks
- Configuration not being loaded from config.json file
- Authentication flow now works end-to-end with JWT tokens
