refactor(auth): remove legacy RESTful user routes and migrate authentication to GraphQL context

- Rename get_current_user to get_current_user_id in auth/deps.py to clarify intent
- Remove legacy /me, /logout routes, and placeholder function from auth/__init__.py
- Remove dependency_overrides from app/main.py
- Update CustomContext to resolve and cache full User objects via db query
