feat: note history modal with restore, diff comparison, and dynamic UI updates

- Complete rewrite of note-history-modal: version list with inline restore/delete,
  split diff view with synced scrolling, rich preview for markdown/richtext/checklist
- Fix restore not updating editor: use key={id-updatedAt} on NoteInlineEditor to
  force remount on restore, and add sync useEffect to reset local state on prop changes
- Add sync useEffect in NoteEditor for external note updates
- Add historyEnabled to NOTE_LIST_SELECT (no more 'Activer' on every modal open)
- Replace browser confirm() with shadcn AlertDialog for delete confirmation
- Add i18n keys: currentVersion, compareVersions, diffTitle, diffSelectHint, deleteVersionDesc
- Install diff + @types/diff for visual line diffing
- Fix MasonryGrid render-phase sync to preserve local sizes
- Update notes-tabs-view merge logic for restored note propagation
- Remove debug console.log from restoreNoteVersion
