Subject: [PATCH] test: stabilize channel affinity cache keys (#8009)

Replace wall-clock identifiers with an atomic sequence and test names so repeated Windows runs cannot share usage-cache entries.

Verification: latest main baseline failed with cumulative counts; patched affinity tests passed -count=20; full service suite and go vet passed.
