Update default settings and enhance ConfirmingPage logic

- Changed default settings to enable two-way and one-shot sync, disable notifications and sync fallback, and adjust confirmation behavior.
- Improved ConfirmingPage to conditionally display the Abort button and update the Accept button text based on the presence of changes in the patch tree.
- Updated logging level in SyncbackStats to warn for better visibility on debug logging hints.
