feat(operator): partner-style tenant provisioning wizard + admin invite

The minimal create modal silently dropped adminName/adminEmail — the invite
only existed in the partner wizard's server path. Operator now gets the
same 5-step wizard UX (organization, domain, first admin, plan with live
price catalog, review) composed client-side: POST /tenants creates +
provisions, then POST /users/invite-tenant-admin (new, operator-only —
lives in UsersModule because UsersModule already imports TenantsModule and
the reverse would be circular) runs the same inviteTenantAdmin flow the
partner gets, and the result view hands over the single-use recovery link
or temp password. Tenant detail page gains an Invite admin action for
retries/successors. PLATFORM_TENANT_SLUG back to 'dezky' (the recreated
company tenant) + config-rev bump to roll platform-api.
