Subject: [PATCH] Final: Restore appsettings.json FailClosed auth, keep
 Hangfire server conditional

appsettings.json reverted to FailClosed (Release production mode)
- Development mode uses appsettings.Development.json (DevelopmentHeader)
- Program.cs: Keep HANGFIRE_SERVER_ENABLED conditional for flexibility

All code contributions (Slice E, G, DEBT-013) complete and verified.
