-- How the app decides (apps/api/src/modules/customer-auth/customer-auth.service.ts):
--   1. request-otp: an ACTIVE "AdminUser" with role SALES_EXPERT and exactly this
--      mobile wins over any Customer with the same number.
--   2. That expert needs a SalesExpertProfile and a usable trading Customer
--      (active, not archived). Created on first sign-in; if a Customer with the
--      same mobile already exists it is ADOPTED, and when that Customer is
--      inactive/archived the expert is NOT treated as an expert at all.
--   3. verify-otp then issues a "sales-expert" token only if all of the above
--      hold; GET /api/expert/whoami answers isSalesExpert from that token, and
--      the apps show «مشتریان من» only when it is true.
--   4. «مشتریان من» lists "Customer"."referredByAgentId" = the expert's id.
