Make flaky RNTester image E2E flows Android-only (#57405)

Summary:
Pull Request resolved: #57405

The `image-blur-prefetch` and `image-wide-gamut` Maestro flows under `packages/rn-tester/.maestro/` were added recently and are too flaky on the iOS E2E job (`test_e2e_ios_rntester`), repeatedly failing builds in the React Native OSS repo. Both rely on `assertScreenshot` color/blur comparisons that don't reproduce reliably on the iOS simulator in CI.

This wraps each flow in a `runFlow: when: platform: Android` guard and adds the `android-only` tag, matching the existing pattern used by `image-progressive-jpeg.yml` and `image-getsize-local-drawables.yml`. On iOS the wrapped `runFlow` is skipped, leaving an empty (passing) flow; on Android the flow runs in full, so Android coverage is unchanged.

The long-standing `image.yml` flow (cross-platform test case in place since 2024) is intentionally left untouched and continues to run on iOS.
