Complete admin backend with login, where all integrations (weather, news, Home Assistant, Vikunja, Unraid, MQTT) can be configured via web UI instead of ENV variables. Two-layer config: ENV seeds DB on first start, then DB is source of truth. Auto-migration system on startup. Backend: db.py shared pool, auth.py JWT, settings_service CRUD, seed_service, admin router (protected), test_connections per integration, config.py rewrite. Frontend: react-router v6, login page, admin layout with sidebar, 8 settings pages (General, Weather, News, HA, Vikunja, Unraid, MQTT, ChangePassword), shared IntegrationForm + TestButton components.
