Summary:
Migrates the pure-logic StyleSheet unit tests from regular Jest (`-test.js`) to Fantom (`-itest.js`), so they run on Hermes inside the real React Native runtime, the same engine that runs this code in production.
Migrated files (all style-processing utilities that run on the client at runtime): `flattenStyle`, `processAspectRatio`, `processBackgroundPosition`, `processBackgroundRepeat`, `processBackgroundSize`, `processFilter`, `processFontVariant`, `processTransform`, `processTransformOrigin`, `setNormalizedColorAlpha`, `splitLayoutProps`.
Notable adaptations:
- `toThrowErrorMatchingSnapshot()` and `toThrowErrorMatchingInlineSnapshot()` are not available in Fantom, so they were replaced with `toThrow('<exact message>')`, preserving the exact error messages that were previously captured in snapshots.
- Removed the now-obsolete file snapshots for `processAspectRatio`, `processTransform`, and `processTransformOrigin`.
- `toMatchInlineSnapshot` (used by `splitLayoutProps`) is supported by Fantom and was kept unchanged.
