⬇️ fix: Image Download Browser Compatibility (#7950)

* fix: Add null check for SelectedTTS in MessageAudio component to prevent rendering issues

* fix: image download browser compatibility with error handling and fallback mechanism

- Updated the downloadImage function to use fetch for improved reliability and added error handling.
- Implemented a fallback to the original download method in case of fetch failure.
- Ensured the download link uses a blob URL for better compatibility with various image types.
