fix(native): fix widget image management and add tests

- Fix `copyBundledAsset` to accept a URI instead of a named bundle asset, resolving via `resolveAssetURL` with support for remote downloads
- Read app group identifier from Info.plist (`ExpoWidgetsAppGroupIdentifier`) instead of a hardcoded string
- Add `pruneWidgetImages(maxAgeSeconds)` to age-based cache cleanup, skipping the widget icon file
- Add `normalizedFileName` helper to sanitize cache keys and a `log` helper with consistent prefix
- Extract `getWidgetIconAsset()` into `widget-assets.ts` so the asset require is testable in isolation
- Add Vitest config for the native app and unit tests covering widget data-fetch, image download, and prune logic
