[ADD] dms: Hoot JS test suite + HttpCase wiring

Fork-only — pre-upstream iteration. Hoot suite for the UX surfaces
introduced in the parent UX PR. Run via HttpCase against the runboat or
locally with --test-enable.

Hoot test suite (tests/test_hoot.py + tests/test_backend_tours.py)
- tests/test_hoot.py wires HttpCase.browser_js with
  /web/tests?...&filter="@DMS" — Hoot's ?filter= defaults to fuzzy
  character-order matching; the double-quoted exact-substring form
  isolates @dms/... test paths from the bundled web-core suite.
- 9 Hoot test files cover the UX surface:
    dms_stat_bar (dashboard tiles + sparklines)
    file_preview_pane (header, load, dispatch)
    preview_handlers (URL builders + dispatch + mimetype fallback)
    preview_registry (registration + score sort)
    file_kanban_buttons / _density / _mount / _list_renderer routing
- defineMailModels() covers the mock-server base because dms depends on
  mail; expect.errors(N) + verifyErrors(patterns) replaces the
  array-of-objects form Hoot rejects.
- Tour: dms_kanban_density_tour covers comfortable / compact / list
  switching + persistence across reloads.
