Description

Stabilizes the RemoteImage unit tests by making mocked image load events explicit in the test file.

The previous setup could let the shared expo-image mock fire a timer-driven default load during tests. This change uses a passive local image mock, keeps unrelated IPFS resolution pending by default, and dispatches image load events through fireEvent.
