Use public APIs in Fantom tests (#58567)

Summary:

Replace eligible React Native deep imports in Fantom tests with package exports, Fantom APIs, DOM globals, and types derived from exported symbols. Keep implementation-specific imports where the public surface does not expose equivalent behavior or compatible Flow types.
