Remove debug logging from file sharing implementation

- Remove all debug logging added during troubleshooting
- Keep the essential fix for EXTRA_STREAM Parcelable handling
- Clean up the code while maintaining the working functionality
- Remove verbose logging from handleIntent, handleUrlAll, handleContent, and handleUnknownText

The file sharing functionality is now working correctly and the code is clean.
