fix(web): preserve per-row aria-labels through RowActionsMenu + test fixes

CI vitest run on 3f8a2c5 surfaced 17 failures across 5 test files; this
commit addresses 15 that are this batch's responsibility.

1. RowActionsMenu now accepts ariaLabel on RowAction. Defaults to label.
   Admin pages (requests/quarantine/users) pass per-row aria-labels
   matching the pre-batch buttons ("Approve Geogaddi", "Resolve Roygbiv",
   "Make alice admin", etc.) so screen readers + tests find them.

2. PlayerBar.test.ts — anchored regex /^(play|pause)$/i so the new
   "Player options" overflow ⋮ doesn't also match /play|pause/i.

3. MobileNavDrawer.test.ts — added vi.mock for $app/state, $app/navigation,
   and $lib/auth/store.svelte (mirrors Shell.test.ts pattern). Without
   these, SvelteKit's notifiable_store helper isn't bootstrapped in
   vitest and the suite fails to load.

The 2 remaining vitest failures are in /admin/integrations Save flow
(putLidarrConfig spy not called). Untouched by this batch and the
recent "Save runs Test first" refactor (bca8622) appears related —
flagging for operator verification, not chasing as a regression.
