feat(auth): enhance session and user deserialization logging

- Added detailed logging for session checks in the auth controller, including session ID and full session object.
- Implemented user existence verification in the deserialize function, with improved logging for user checks and database query results.
- Enhanced the serialize function to log the serialized user object and completion of the serialization process, improving traceability in authentication workflows.
