chore: Migrate sample apps and perf tests from ESLint to oxlint

Remove ESLint from all sample apps (react-native, react-native-macos,
expo) and performance test apps (TestAppPlain, TestAppSentry). Replace
with lightweight oxlint configs for samples that had lint scripts.

Also clean up root package.json:
- Remove es-iterator-helpers resolution (no longer needed)
- Remove eslint-plugin-ft-flow resolution
- Remove @typescript-eslint/typescript-estree minimatch resolutions

This fully removes ESLint from the repository.
