Refactor module middleware initialization logic.

Replaced `getMiddleware` with `onServerInit` for streamlined middleware registration. Updated `AppAuth` to automatically register its authentication middleware. Added a test case to verify middleware registration. Removed redundant cookie renewal logic from `AdminController` and made related adjustments across modules.
