Barcode Betty ec9deb515b fix(api): accept DATABASE_URL as fallback for shared DB with auth service
API config.py now reads CARTSNITCH_DATABASE_URL first, falls back to
DATABASE_URL (which the infra K8s overlay sets for all pods), and finally
falls back to the hardcoded default. Also normalizes plain postgresql://
to postgresql+asyncpg:// for the asyncpg driver.

Fixes CAR-510.
