The script-run head and the suite summary now display, while a load run
repeats: the elapsed time so far, the average per completed iteration and
the estimated time left (testLoadTiming / testDurationText /
testIterAvgText), recomputed on every 2 s status poll. A finished run
keeps the server's final elapsed_ms/avg_ms (no estimate), and before the
first completed iteration only the elapsed time is shown - no bogus
average or ETA.
The timing is client-side over the existing load block (started, done,
iterations), so it works with the running server as well; no server
change is needed.
Tests: the timing math and the two formatters, the script head render and
the suite summary render (3 new). 1061 Python + 1074 frontend.
