…rmanent (docmost#201)

"Temporary notes" with a death timer: created via a dedicated hourglass button
in the space-tree header, a note auto-moves to Trash after a configurable X
hours (default 24) unless explicitly made permanent ("structure or die").

Reuses existing mechanisms, mirroring is_template and the trash-cleanup job:
- New nullable column pages.temporary_expires_at (NULL = permanent; non-NULL =
  frozen deadline) + partial index for the sweep; workspace column
  temporary_note_hours (default via DEFAULT_TEMPORARY_NOTE_HOURS = 24).
- create-page DTO `temporary` flag; the deadline is frozen at creation so later
  setting changes never reschedule existing notes.
- POST /pages/toggle-temporary (mirror of toggle-template): arm/clear the timer,
  CASL-guarded via validateCanEdit, cross-workspace NotFound defense-in-depth.
- TemporaryNoteCleanupService: hourly @interval sweep that soft-deletes expired
  notes through the exact PageRepo.removePage path (recursive over children,
  emits PAGE_SOFT_DELETED), attributed to the creator; idempotent via
  deletedAt IS NULL filters.
- restorePage clears temporary_expires_at so a restored note can't be re-trashed.
- Workspace setting temporary_note_hours (audit-tracked) + a hours editor in
  workspace General settings.
- Client: second create button, orange tree icon, tree + page-header menu toggle
  ("Make temporary"/"Make permanent"), an open-note banner with a rescue action,
  and en/ru i18n.

Tests (unit): toggle-temporary controller (toggle/explicit/permission/cross-ws +
DTO validation), cleanup-job sweep (selection filters, per-note removePage,
error isolation), and a migration up/down sanity. Server tsc, client tsc -b,
and the page+workspace jest suites are green.

Must-fix:
- CHANGELOG: add [Unreleased]/Added entry for temporary notes (docmost#201).
- temporary-note-cleanup: re-check temporary_expires_at at deletion time so a
  concurrent "Make permanent" (sets it NULL) between the batch SELECT and the
  per-row removePage wins the race and the note is not trashed. Add unit tests
  for the make-permanent and already-trashed race windows.

Non-blocking review items:
- temporary-note-cleanup: cap the sweep batch (LIMIT 500) so a large backlog is
  not loaded into memory; remainder drains on the next hourly run.
- client: extract duplicated post-toggle cache sync into
  syncTemporaryExpiresInCache() shared by the header menu and the banner.
- Remove the tautological migration spec that mocked the whole Kysely builder.
- Tests: cover create() frozen temporaryExpiresAt (workspace override + NULL
  default fallback + non-temporary skips lookup) and restorePage disarming the
  timer (temporaryExpiresAt: null).

Deferred (forward-looking, non-blocking): extract
PageService.computeTemporaryExpiresAt() to dedupe the deadline formula and drop
the @InjectKysely from PageTemplateController; replace migration unit test with
a real Postgres up/down integration test.

…ocmost#201)

develop merged 20260626T130000-share-aliases; rename this PR's migration to
20260626T140000 so the two no longer share a timestamp prefix.
