feat: add health check and restore frontend routes

Health check endpoint: - Add /health endpoint that pings database with 2-second timeout - Returns 200 when DB connected, 503 when unavailable - Provides true end-to-end health verification Frontend routes restoration (routes removed in c5f327b): - Add public routes: /, /login, /register with smart auth detection - Add redirect routes: /bookshelf, /dashboard - Add admin routes: /admin, /admin/profile, /admin/library - Add SSR routes: /api/devices-page, /api/conflicts-page - Add 'FRONTEND ROUTES - DO NOT DELETE' comment block to prevent future removal Docker Compose healthcheck: - Update to use curl on /health endpoint (pg_isready not in Alpine) - Add 10s start_period for app initialization - Accurately reflects app + database health status All changes maintain backward compatibility and existing API behavior.
