- 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

"""Authentication service for Aniworld.
|
|
|
|
Responsibilities:
|
|
- Setup and validate a master password (hashed with bcrypt via passlib)
|
|
- Issue and validate JWT access tokens
|
|
- Track failed login attempts and apply temporary lockouts
|
|
- Provide simple session model creation data
|
|
|
|
This service is intentionally small and synchronous; FastAPI endpoints

can call it from async routes via threadpool if needed.
