git-secret-scanner-blocks-alembic-ini-db-url

The pre-commit secret scanner flags database connection URLs written directly in alembic.ini. The fix is to leave the sqlalchemy.url field as a placeholder (e.g. postgresql+psycopg2://) and rely solely on the RSAME_DATABASE_URL env var in alembic/env.py. Attempting to commit a real or dev URL will fail the hook.
