test: expand BASE service group coverage

Add BASE probe coverage for unregistered, experimental, and vendor
service group IDs, plus an invalid BASE service ID case.

This complements the existing positive BASE service tests and relies
on the shared harness ACK header checks to verify token, service group,
and service ID mirroring for normal requests.
