feat(operator): create direct tenants from the operator portal

The operator could list and inspect tenants but had no create flow — tenant
creation only existed as the partner-portal wizard, which always attaches a
partnerId. Platform-api's POST /tenants (platform-admin only, no partner
field) was already built for this; add the missing UI: a New tenant modal on
the tenants page (slug, name, plan/cycle/currency/seats, optional primary
mail domain + first-admin invite) and the server proxy route. Operator-created
tenants are direct customers; attach a partner later if needed.
