Update pyproject.toml and logging for stricter rules and improved error handling

- Ignored additional Ruff rules for test files, SQLAlchemy fixtures, and FastAPI-specific naming conventions.
- Suppressed passlib bcrypt warnings in `core.auth`.
- Improved exception handling in session marking with explicit logging for token parsing failures.
