ci: add more paths to trigger Docker builds

- Added docker-entrypoint.sh to trigger paths
- Added drizzle/** for database migrations
- Added scripts/** for database management scripts
- Added src/** for source code changes

This ensures Docker images are rebuilt when critical runtime
files change, not just package dependencies.
