extractArchivePath only stripped the "Archive written to " prefix when
the string ended in ".tar.gz", but SAT packs write bare run directories,
never actual tar.gz archives. Any task routed through an
ActionResult-wrapping pack function (e.g. RunNvidiaAcceptancePackWithOptions,
used by the DCGM L1-L4 diag task) passed the whole prefixed string into
ReadSATOverallStatus, which then failed to find summary.txt and silently
returned "", masking real job failures as task-level "done".
Strip the prefix directly instead of gating on a suffix that SAT run
dirs never have.
