Drag-to-reorder service cards (iOS jiggle mode)

Long-press a service tile (~500 ms) → grid enters edit mode: every
card jiggles, a floating "تم / Done" pill appears, and cards become
draggable via @dnd-kit. Drop on another tile to reorder. Tap Done or
outside the grid to persist; the new order is shared globally via
servicesTable.sortOrder.

Backend
- POST /api/services/reorder (admin-gated, requireAdmin)
- Validates full-set match (no missing/dup/unknown IDs)
- Transactional sortOrder rewrite — no partial writes
- Route registered before /services/:id to avoid path-param collision
- OpenAPI op + ReorderServicesBody Zod schema → regenerated client

Frontend
- artifacts/tx-os/src/pages/services.tsx rewritten
- PointerSensor (distance 6) + TouchSensor (delay 150 ms) — long-press
  and tap-to-open stay distinct
- touch-none only applied while in edit mode so normal scrolling is
  unaffected outside it
- exitEditMode awaits mutation + invalidate before flipping editMode,
  preventing snap-back from stale react-query cache
- exitingRef guard against duplicate exit calls (Done button +
  outside-tap handler firing for the same gesture)
- Non-admins can enter edit mode (haptic affordance) but local reorder
  is silently reverted on exit
- i18n: services.editMode.{done,hint,saveFailed} added to ar.json/en.json

Pre-existing unrelated typecheck errors in push.ts and
executive-meeting-font-settings.ts are not touched by this change.
