Add Native File Dialog support and enhance file dialog management

- Introduced a feature flag to toggle between Native File Dialog (NFD) and bespoke file dialog implementations.
- Updated FileDialogWrapper to utilize the feature flag for opening files and folders, improving cross-platform compatibility.
- Enhanced the UI to allow users to configure the file dialog mode, providing better user control over file handling.
- Added new methods for testing both NFD and bespoke implementations directly from the UI, improving testing capabilities.
- Updated test management to include options for enabling/disabling individual tests, enhancing flexibility in test execution.
