The fingerprint-change-warning spec pinned a deliberately bogus
fingerprint on the worker's seeded SSH executor to exercise the
mismatch UI, then exited without resetting it. Later specs in the
same worker that launched real tasks against the same executor
(workdir-per-profile R1/R2 in alphabetical order) failed at SSH dial
time with host-key-changed, since the executor was still pinned to
the bad value.
Wrap the assertion in a try/finally that restores the original
fingerprint from seedData when the test ends, so the worker leaves
the executor in the same state it inherited.
