Include user information and token expiration in authentication responses

Updated the `Token` schema to include `user` data and `expires_in` field. Adjusted backend `auth_service.py` to populate these fields while generating tokens. Replaced `getCurrentUserInfo` with `getCurrentUserProfile` in the frontend and disabled ESLint for generated files to suppress warnings.
