parity(api,apps): security hotfix stage 2 - real customer sessions, close IDOR

Stage 1 narrowed GET /customers but did not close the leak: the response still
carried every customer id, and /customers/:id, /:id/orders and
/:id/ledger-entries were still public, so the full customer book was still two
requests away. The user caught this. Stage 2 deletes the id-bearing surface.

Customer JWT, separate from the admin one (T1):
  - new src/modules/customer-auth/ with its own passport strategy,
    CustomerJwtGuard, @CustomerAuth() and @CurrentCustomer()
  - signed with JWT_CUSTOMER_SECRET, and every token carries typ:'customer'
    which the strategy verifies; both checks are present deliberately
  - customer state re-read per request, so deactivating takes effect at once
  - mirrors the reference's own split: auth:api vs auth('api-customer')

Real OTP (D6), porting ApiMobileController::userAuth/userVerfiy (:39-64):
  - new CustomerOtp table, additive migration, nothing existing touched
  - parity behaviour: rand(1000,9999), active-customer filter, faTOen digit
    normalisation on both number and code, rejection on mismatch
  - approved improvements over the reference: bcrypt-hashed code, 2-minute
    expiry, 5 attempts then lockout, single use, send throttle (60s per
    number, 5/number and 20/IP per 10 min), and no number enumeration

Routes removed, replaced by token-derived equivalents:
  GET customers, customers/:id, /:id/orders, /:id/ledger-entries
    -> GET customer/me, customer/me/orders, customer/me/ledger-entries
No route accepts a customer id any more, so the IDOR is closed structurally
rather than by a check. The admin panel was unaffected (admin/customers-omde/*).

Both apps migrated in the same commit per the v1/v2 parity rule: token-based
session store, Bearer header, 401 -> clear session and route to login, real
two-step OTP login. Each app keeps its own markup and styling; only logic moved.

Tests: auth-smoke.sh extended with the stage-2 assertions, 46 passed 0 failed
against a live server. jest installed dev-only (user-approved) so pnpm test
works for the first time: 7 passed covering faToEn, which moved to its own
digits.ts to be testable without booting Nest. Typecheck clean on api,
user-app and user-app-v2; both apps build.
