## Task #80 — Tell receivers when an order is no longer available to claim
### Problem
When a receiver tried to act on an order that had already been cancelled, completed,
or claimed by someone else, the UI showed a generic "Could not complete the action"
toast. The stale card also stayed in the list, requiring a manual refresh.
### Changes
**artifacts/api-server/src/routes/service-orders.ts**
- PATCH /orders/:id/confirm-receipt: after a failed atomic claim, query the current
order status; return 409 `order_unavailable` if it's cancelled/completed (vs the
existing 409 `already_claimed` for when it was grabbed by someone else first)
- PATCH /orders/:id/status (preparing/completed branch): terminal-state check runs
BEFORE permission gating — returns 409 `order_unavailable` when order is already
cancelled/completed instead of ever hitting 403 Forbidden
- PATCH /orders/:id/status (cancel branch): same — terminal-state check moved to
the top of the branch so non-admin receivers trying to cancel an already-terminal
order get 409 `order_unavailable` (not 403 Forbidden which would never let the UI
remove the stale card)
**artifacts/tx-os/src/pages/orders-incoming.tsx**
- handleConfirmReceipt onError: distinguish 409 `order_unavailable` from
`already_claimed`, show specific toast, remove stale card via invalidate()
- handleSetStatus onError: same pattern — specific toast + invalidate() on
`order_unavailable`
- handleCancel onError: same pattern
**artifacts/tx-os/src/locales/en.json + ar.json**
- Added `incomingOrders.orderUnavailable` ("This order is no longer available" /
"هذا الطلب لم يعد متاحاً")
## Bonus fix — Disabled app disappears from admin panel (user-reported)
### Problem
When an admin disabled an app via the toggle, the app disappeared from the admin
panel too (isActive filter applied to everyone), making it impossible to re-enable
without direct DB access.
### Changes
**artifacts/api-server/src/routes/apps.ts**
- getVisibleAppsForUser: admins now receive ALL apps including inactive ones via
conditional $dynamic() Drizzle query; non-admins still only see active apps
**artifacts/tx-os/src/pages/home.tsx**
- Filter orderedApps to only active apps before rendering so inactive apps don't
appear on the home screen even for admins
**artifacts/tx-os/src/pages/admin.tsx**
- Inactive app cards show reduced opacity + a "Disabled/معطّل" badge
**artifacts/tx-os/src/locales/en.json + ar.json**
- Added `admin.appDisabled` ("Disabled" / "معطّل")
