Removed announcementBar feature flag

[EvanHahn]

ref f9f5f72

This change should have no user impact.

The announcementBar feature flag has been enabled since 2023. We can remove the flag and assume it's always on.

Note

Low Risk
Small flag-removal change that mainly deletes gating and updates tests; risk is limited to unintentionally exposing /api/announcement where it was previously blocked by misconfiguration.

Overview
Removes the announcementBar labs feature flag from the admin feature service and from shared labs GA flag handling.

The members /api/announcement route is no longer protected by labs.enabledMiddleware('announcementBar'), and related test fixtures/snapshots are updated to stop expecting or setting the flag in config/labs payloads.
