Michael Chihlas 7d96807fb1 Add production logging, datetime fixes, and session tests
DateTime Timezone Handling (Critical Bug Fix):
- Updated all models to use DateTime(timezone=True) for PostgreSQL
- Changed datetime defaults to lambda: datetime.now(timezone.utc)
- Fixed mixing of timezone-aware and timezone-naive datetime objects
- Resolved Internal Server Errors in session completion endpoint
- Affected models: User, Team, Tree, Session, Attachment

Production Logging System:
- Created logging_config.py with structured logging setup
- Added log rotation (10MB files, 10 backups) for production
- Implemented RequestLoggingMiddleware with correlation IDs
- Added ErrorLoggingMiddleware for comprehensive error tracking
- Integrated logging into main.py application startup
- Supports dev/prod modes with appropriate log levels

Integration Tests - Session Workflow:
- Created test_sessions.py with 12 comprehensive tests
- Session lifecycle: create, update, complete
- Session export in multiple formats (markdown, text, HTML)
- Error handling and authorization checks
- Added pytest.ini with coverage configuration
- Added requirements-dev.txt with pytest dependencies

Following 2026 FastAPI best practices for timezone handling and structured logging.
