+/* Internal purchasing requests — shared module for every *.designerwallcoverings.com

+                                 stock/price requests AUTO-EMAIL the vendor via

+   POST /api/request/preview   → compose the exact email (no insert, no send).
+   GET  /api/requests          → recent requests for this vendor (internal queue view).
+
+   Hard rules baked in:
+   - NEVER include a client name — emails reference our account number + REQ only.
+   - Vendor emails go out ONLY on an explicit user click behind Basic Auth; the
+     george external-send guard token is passed because that click IS the approval.
+   - No vendor email on file → request is still logged (status no_email) and the
+     caller is told to phone the vendor instead. */
