feat: enhance RichEditor with logging and improve NotesPage editor synchronization (#9817)

* feat: enhance RichEditor with logging and improve NotesPage editor synchronization

- Added logging for enhanced link setting failures in RichEditor.
- Improved content synchronization logic in NotesPage to prevent unnecessary updates and ensure cleaner state management during file switches.
- Updated markdown conversion to handle task list structures more robustly, including support for div formats in task items.
- Added tests to verify task list structure preservation during HTML to Markdown conversions.

* feat: enhance Markdown preview interaction in AssistantPromptSettings

- Added double-click functionality to toggle preview mode in the Markdown container, preserving scroll position for a smoother user experience.
