While the add-on is down the batteries are at 0 W (it sets 0 W when it
stops; the ESP32 watchdog after 30 s), so the import before its first
reading was the house, not the aim. Those seconds now count at
gap_w(limit, the import seen first), and after a restart the restored
reading's held 30 s is topped up the same way. Status row: "counted as
high use". Tests take the pre-start import as the house (batteries at
0 W) and add restarts of 10/60/150 s with a restored averager.
