Give a run a timestamp for when it last moved

The collection had 'created' and nothing else, so the card read a field that was
not there, got NaN, and called every live run stalled. status alone cannot answer
'is it still alive' -- a killed process leaves its record saying running for ever
-- so the honest signal is when it last updated.

And PocketBase hands back '2026-09-10 09:42:49.664Z': a space instead of the T,
with the zone already on the end. Appending another Z made every parse NaN.
