Add direct regression coverage for the Responses-sidecar lease cleanup.

The changed test calls releaseCodexAuthContextProbeLease directly. It does not execute prepareResponsesSidecarAuth or this finally block. Existing Responses-sidecar tests do not assert that ResolvedOpenAiForwardSidecar.releaseProbeLease returns the lease after an invalid-image or no-upstream vision exit.

Add a focused test that reaches this block through such an exit and verifies that a later probe acquires a replacement lease.

focused regression coverage for prepareResponsesSidecarAuth that reaches the
finally block through an invalid-image or no-upstream vision-only exit, then
verifies ResolvedOpenAiForwardSidecar.releaseProbeLease returns the lease by
asserting a subsequent probe acquires a replacement lease. Do not test
releaseCodexAuthContextProbeLease directly; exercise the production cleanup path
instead.
