- Add OAuth2 client for Authentik integration - Implement JWT token generation and validation - Add refresh token support with database storage - Update database schema with oauth_subject, oauth_provider, and refresh_tokens table - Create auth package with config, jwt, oauth, and token management - Add OAuth endpoints: /auth/login, /auth/callback, /auth/refresh, /auth/logout - Update AuthMiddleware to support both JWT and API key authentication - Add user helper functions for OAuth user creation and retrieval - Add .env.example with OAuth configuration template API keys still work for CLI compatibility while JWT tokens support web/mobile clients.
