fix: remove @testing-library/react-hooks and migrate to @testing-library/react-native

- Replaced react-hooks import with react-native renderHook/act in ThemeContext.test.tsx
- Replaced react-hooks import with react-native renderHook/act in useFilteredSubscriptions.test.ts
- Updated ThemeContext test 'throws outside provider' to match new error handling behavior
- Removed @testing-library/react-hooks from package.json (incompatible with React 19 types)
- All tests passing after migration
