Subject: [PATCH] test(documents): rewrite list page test with behavioral
 assertions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces 3 setTimeout sleeps with click + auto-wait / vi.waitFor on
the bulk-edit-all flow, and converts 14 .not.toThrow smoke tests into
behavioral assertions:

- Advanced-filter labels (Schlagworte/Absender/Empfänger/Von/Bis) for
  every hasAdvancedFilters() branch (senderId, from, to, tags)
- Collapsed advanced section when all filters are at falsy defaults
- Search input value reflected via two-way binding
- BulkSelectionBar surfaces count when store has entries
- bulk-edit-all populates selection store on success

Runtime: 48s → 3.8s. Addresses Sara's blockers on PR #505.
