test: remove obsolete mobile-swipe-delete.test.ts

The file tested a Fase 2b.5 interaction — full-swipe commits a delete
with an undo toast — that Fase 5.10 replaced. Swipes on the list detail
view are now a symmetric check/uncheck toggle; delete lives in the
double-tap overlay and in selection mode. The two tests were
describe.skip'd since Fase 5.10 and the UX they describe doesn't exist
anymore.

The swipe-toggle gesture that replaced it is still untested at the E2E
level because Chromium touch emulation can't drive pointer/touch events
into Svelte's component handlers reliably. Adding `playwright install
webkit` to CI would unblock a fresh `mobile-swipe-toggle.test.ts` with
M-06 swipe-right-check, M-07 swipe-left-uncheck, and M-08 wrong-
direction snapback. Noted in plan/fase-5-mobile-ux.md §5.10.b.

Verification
  just test-all → 228 green, 2 skipped (both are the upstream
  Realtime presence bug in realtime-presence.test.ts; everything else
  passes).

- * iOS Safari engine) handles this correctly but isn't shipped with the current
- * install. Re-enable when we add `playwright install webkit` to CI.

- * The red-zone swipe-delete logic itself is implemented in

- * covered functionally by the D-04 desktop hover-delete test plus the unit
- * tests in `src/lib/sync/undoQueue.test.ts`.
