fix: respect dev mode in entrypoint database initialization

- Update entrypoint.sh to check DEPLOYMENT_MODE before initializing database
- DEV mode: calls initialize_dev_database() which resets the database
- PROD mode: calls initialize_database() which preserves existing data
- Adds clear logging to show which mode is being used

This ensures the dev database is properly reset on container startup,
matching the behavior of the lifespan function in api/main.py.
