parity(api,apps): security hotfix stage 1 - close unauthenticated write paths

Authorised by rulings D7 and T1-T3 in docs/parity/DECISIONS.md. This is the
CLAUDE.md section 3 carve-out: matching the reference here would keep a money
write path open to anonymous callers.

Closed, each behind the rid the legacy vocabulary already had:
  GET   accounting/customers/:id/balance    -> wallet.list
  POST  accounting/customers/:id/reconcile  -> wallet.charge
  POST  accounting/repayments/gold          -> document.create
  POST  accounting/repayments/rial          -> document.create
  POST  accounting/entries/:id/confirm      -> document.list.confirm
  PATCH orders/:id/status                   -> order.list.sts.submit

Four of the accounting routes WRITE to the ledger. The order-status route was
worse in kind: its DTO takes a client-supplied actorAdminUserId, so an
anonymous caller could move any order and pin it on any admin. It had no
caller - the admin panel posts to admin/orders/status.

GET /customers kept its public status (both apps' login still matches the
phone number in the browser) but now selects only id/mobile/isActive/
isArchived. It previously returned every active customer's full name, national
code, both debts, credit limit and the URLs of their identity-document scans.
CustomerSummary narrowed in BOTH user apps in the same commit, per the
v1/v2 parity rule.

Not changed: /uploads stays public per ruling T2. The filename check requested
alongside it passed unchanged - md5(time + name + uuid), no directory listing.

Tests: apps/api/scripts/auth-smoke.sh asserts 401 without a token, 403 with a
low-privilege token (ut 88, 5 unrelated rids) and pass-through for a super
admin on every closed route, plus that the public routes still answer 200 and
that GET /customers exposes only the four login fields. 23 passed, 0 failed
against a live server. Typecheck clean on api, user-app and user-app-v2.

## T1 — Customer authentication: a separate JWT strategy (option **الف**)
Approved. Conditions:
1. **Separate secrets** — customer tokens are signed with `JWT_CUSTOMER_SECRET`,
admin tokens with `JWT_SECRET`.
2. **A `typ` claim is checked in both guards** — `typ: 'admin'` vs `typ: 'customer'`.
3. **Mandatory cross-token tests:** a customer token on any admin route → 401;
an admin token on a customer route → rejected, unless deliberately allowed.
4. **Token lifetime and logout must be compared against the reference and
recorded here** (see below).
5. **No IDOR** — customer routes that return personal data derive the customer
from the **token**, never from an id in the request.
### Reference comparison — token lifetime and logout
| Aspect | Reference | Target (current) | Decision |
|---|---|---|---|
| Customer token | `api_token = Str::random(60)`, a random opaque string stored on the customer row (`ApiMobileController.php:60-62`) | none | new customer JWT |
| Expiry | **none** — the reference token never expires; it is reused on every login if already set | admin JWT `JWT_EXPIRES_IN`, default `12h` | customer JWT gets an explicit expiry (deliberate improvement over the reference) |
| Logout | the reference has **no logout endpoint**; the app drops the token client-side | apps clear `localStorage` | keep client-side clear; note that a stolen token stays valid until expiry |
| Rotation | the reference issues a new token **only if `api_token` is null** — logging in twice returns the same token forever | n/a | issue a fresh token on every verify |
The last three rows are **deliberate improvements over the reference**, approved
by the user in the same message that approved D6. Recorded so the matrix does not
later flag them as parity gaps.
## T2 — Uploaded files stay public
**Ruling:** `/uploads` is not touched. No allow-list, no signed URLs, and the
"private folder" stage is dropped.
**Recorded verbatim at the user's request:**
> «فایل‌های آپلودی شامل مدارک عمداً عمومی هستند — تصمیم مالک پروژه»
> (Uploaded files, including identity documents, are deliberately public — the
> project owner's decision.)
### The light check the user asked for — result: ✅ already correct
| Check | Result | Evidence |
|---|---|---|
| Filenames unguessable? | **Yes.** `md5(Date.now() + originalname + randomUUID())` + the original extension | `src/modules/admin-uploads/admin-uploads.service.ts:53` |
| Sequential or original name on disk? | **No.** `originalName` is kept only as a DB column, never as the filename | `admin-uploads.service.ts:62` |
| Directory listing? | **No.** `PublicUploadsController` only resolves a single `:filename`, and `resolveStoredUpload()` rejects `.`/`..` and anything resolving outside the upload dir | `public-uploads.controller.ts:17`, `upload-path.ts:34-49` |
Nothing to change. No existing files were moved.
## T3 — Two-stage hotfix
Approved, with the condition that `GET /customers` be checked first.
**Check result:** the apps **are** dependent on it. Its only consumer is
`LoginView.vue:131` in both apps, and `CustomerSummary` is used nowhere else
(verified by grep). The fields actually read are `mobile`, `isActive`,
`isArchived`, then `session.login(id, mobile)` — four fields.
So per the ruling: stage 1 strips the sensitive fields and keeps the route; stage
2 removes the route when login moves to OTP.
