fix: dynamic note restore without page reload + fix note list sync bugs

- NoteHistoryModal: remove window.location.reload(), use onRestored(restored) callback
- NotesTabsView: revert sync derivation to useEffect, add prevNotesRef to detect
  server-side content changes (restore) vs local edits — fixes note disappear bug
  and cross-notebook notes appearing after refresh
- NoteInlineEditor key: include updatedAt so restoration remounts editor with fresh content
- note-card: render title/content/labels from note prop directly, not optimisticNote
