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.

Summary: Migrates the remaining StyleSheet unit tests from regular Jest (`-test.js`) to Fantom (`-itest.js`): `normalizeColor`, `processColor`, `processColorArray`, `processBackgroundImage`, and `StyleSheet`. These run on the React Native client at runtime, so they now run on Hermes in the real runtime. Adaptations (no coverage weakened): - Replaced `jest.spyOn(console, ...)` with manual save/replace/restore of the `console` method (Fantom does not provide `jest.spyOn`), both to assert and to suppress expected output. - Replaced the module-mock delegation check in `normalizeColor` (which relied on `jest.mock`) with a behavioral assertion on the real implementation. - These tests run on the Android runtime under Fantom (Jest defaulted to iOS); platform-specific requires were moved next to their platform branches where needed.
