feat: scoped mark-all-read, share enhancements, notification z-index

- Mark all as read now scopes to current feed/folder instead of all
- Added undo button to mark-all-read toast notification
- Share notes can be toggled between public and private visibility
- Track share view count and display in shares list
- Activity-based share expiry: views reset the expiry timer
- Fixed notification panel z-index layering behind content area
