[BWA-196] iOS 26 Authenticator Stuck On Loading Page

### Steps To Reproduce

After restoring an iOS backup to a 17 Pro Max:
1. Updated Authenticator to 2025.9.0 (188)
2. Changed setting to lock immediately and FaceID to unlock
3. (Maybe related?) Set up syncing with Authenticator in Bitwarden Password Manager Settings

### Expected Result

Authenticator loads when opened up and unlocks with FaceID.

### Actual Result

Authenticator stays stuck on the Authenticator startup logo, as seen in the screenshot below. Restarted iPhone several times (and also force closed the app) hoping that would resolve it, but no luck.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

No source file, test, or entry point is named in the issue. First reproduce the startup hang using the listed iPhone, iOS, app version, lock, FaceID, restore, and sync conditions; done means Authenticator reaches its usable screen and unlocks with FaceID instead of remaining on the startup logo.
