refactor(db): add database indexes, missing init files, Makefile, and Docker improvements

- Added indexes on all foreign key columns (scan_id, project_id, asset_id)
- Added index on scan session status for query performance
- Created missing bugfinder/agents/__init__.py and tests/__init__.py
- Created Makefile for developer workflow
- Improved Dockerfile with non-root user and healthcheck
- Added PYTHONUNBUFFERED=1 for better container logging
