feat: add provisioning fields to tenants + license revoke

Adds server_endpoint and provision_error columns to tenants table (V011 migration),
updates TenantEntity and TenantResponse with new fields and a from() factory,
adds revokeLicense() to LicenseService, and updates TenantController to use the factory.
