- Added models for `OAuthClient`, `OAuthState`, and `OAuthAccount`. - Created Pydantic schemas to support OAuth flows, client management, and linked accounts. - Implemented skeleton endpoints for OAuth Provider mode: authorization, token, and revocation. - Updated router imports to include new `/oauth` and `/oauth/provider` routes. - Added Alembic migration script to create OAuth-related database tables. - Enhanced `users` table to allow OAuth-only accounts by making `password_hash` nullable.
