- Add `useBulkDeleteSentNotes` hook that fans out parallel DELETE
/notes/:id calls via Promise.allSettled and returns {ok, failed}
so the UI can render a precise toast on partial failure. Caches
invalidated once via `invalidateNotesAndFolders`.
- NotesPage: page-level `sentSelectionMode` + `selectedSentIds`
Set, auto-reset when navigating away from the Sent tab.
- Header gets a Select / Cancel toggle, gated on
`view === "sent" && filteredSent.length > 0`.
- New sticky bulk-action bar above the sent list with count,
select-all/clear toggle, and Delete button.
- SentList accepts optional selectionMode/selectedIds/onToggle
props; cards swap onClick (open → toggle) and show a Checkbox
overlay + rose ring when checked.
- AlertDialog confirms before deleting; toast reports all-success,
partial, or all-failed using pluralized i18n keys.
- New i18n keys under `notes.bulk*` in ar.json + en.json.
No server changes (existing DELETE /notes/:id is reused).
Out of scope (per task spec): undo, bulk-archive, bulk endpoint,
multi-select on Active/Received/Archived tabs.
