feat: pause auto-refresh when SetVisibilityDialog is open

- Pause auto-refresh when SetVisibilityDialog becomes visible
- Resume auto-refresh when dialog is closed
- Prevents background refresh interference during visibility settings
- Fix type compatibility for visibilityDialogMembers data structure

This ensures users can interact with the visibility dialog without
the members list refreshing in the background, providing a better
user experience for setting member visibility preferences.
