feat: Synchronize shaarli-pin tag with isPinned status in FeedViewModel and PinnedViewModel

- Add automatic shaarli-pin tag management when toggling pin status
- Add shaarli-pin tag when pinning a link (if not already present)
- Remove shaarli-pin tag when unpinning a link
- Update both pin status and tags atomically in togglePin() methods
- Bump version to 2.1.7 (VERSION_CODE 22)
