fix(app): re-check the sales-expert flag on every dashboard visit

The "سفارش مشتریان" / "مشتریان من" entries are shown from session.isSalesExpert,
which was fetched from /expert/whoami only once, at sign-in. A slow or failed
request (silently swallowed) left the flag false until the next login, so an
expert saw a customer-only menu. The dashboard now asks again on mount and on
every re-activation, and keeps the current value when the request fails.

Rebuilds user-app and user-app-v2 dist.
