fix(fires): report a 00:45 UTC detection as 00:45, not "45"

get_active_fires joined FIRMS acq_date and the unpadded acq_time, so a
detection at 00:45 UTC came back as "2026-01-01 45". The row now uses
acquisitionMsUtc, which pads the time, and reports an ISO UTC timestamp
like the other tool times.
