fix: prevent app hang on launch by adding fallback in getExtensionStatus

- Add fallback to .disconnected status when no manager is found - Add error handling to return .disconnected on loadAllFromPreferences() failure - Prevents UI hang when getExtensionStatus() is called during app initialization - Ensures completion handler is always called, even on error - Improves app startup reliability
