Fix database migration path issues for container environment

- Updated migrations/env.py to handle Python import paths correctly
- Fixed app/db/base.py to import all required models
- Updated database path in app/db/session.py to work in both local and container environments
- Updated SQLite path in alembic.ini for container compatibility
