Data plane and secret hygiene

Additive hitl.* schema on the shared Postgres (hitl.tickets); kg.* and gtins.* are untouched by this service.

The connection string lives ONLY as a Container App secret. It is never committed, never written into deploy files, never echoed, and never logged. Application code reads process.env.DATABASE_URL and nothing else — see server.js and console.js. Deploy docs reference the DSN as a placeholder only. Verified by a full-history credential scan: zero literal secret values.
