Set application_type in runAuthMigrationClient

The SEP-2352 authorization-server-migration handler constructs its own
ConformanceOAuthProvider (not via withOAuthRetry), so it was missing
application_type after rebasing onto main. The scenario does DCR twice
(old AS, new AS) and the SEP-837 check fires on each.
