test(forms): add unit tests for FormTextarea and FormSelect components

- Add comprehensive test coverage for FormTextarea and FormSelect components to validate rendering, accessibility, props forwarding, error handling, and behavior.
- Introduced function-scoped fixtures in e2e tests to ensure test isolation and address event loop issues with pytest-asyncio and SQLAlchemy.
