Unified admin

This app runs on its own port. Sign in with an account that has the ADMIN role (same QuickDeal database).

• Default: real sign-in — this app uses the same qd_session cookie as QuickDeal (ADMIN role in the database). Set ADMIN_SCAFFOLD_AUTH=1 only on trusted local networks; it is ignored in production builds.
• Cross-port localhost cookies do not match: use shared .quickdeal.com hostnames in dev, or scaffold (local only).
• QuickDeal consumer site: open login.

After signing in on a host that shares the session cookie with this app, open the admin base URL (e.g. /).
