test: clear the sync-wait floor in the format matrix per-case timeout (#381)

The matrix per-case timeout equaled the 30s SYNC_WAIT_MS test floor, so a contended job that rode the full sync-wait window before returning a valid 202 raced the timeout and was flagged as a hang. Raise it to 60s. extract-pages on tiny.pdf took 30051ms in the PR run, just over the old 30000ms limit.
