- Added MISTRAL_API_KEY validation in deploy.sh with fatal error if missing
- Added --force-recreate flag to recipe-api restarts in disable/enable receipt trace scripts
- Added .env file existence check in rebuild_flutter.sh
- Added API service recreation logic in deploy.sh when backend/importer services are updated
