alembic-ini-db-url-secret-scanner-catches-plaintext

Secret scanner (gitleaks/trufflehog) flags any dev DB URL in alembic.ini, even in plaintext sqlalchemy.url = lines with non-production credentials. Correct pattern: leave sqlalchemy.url blank in alembic.ini and read from RSAME_DATABASE_URL env var inside alembic env.py. The env.py already handles this — the ini field just must not contain the URL.
