UX-13 P2 review
7be09197d4
1. Discard reloads /config/model: after a stale save the page kept the
new fingerprint with the old values, so Discard + Save overwrote the
other surface's change without a 409.
2. Removing cards back to one restores the stored inverter shape, so a
flat site stays flat after add + remove.
3. A choice the page can only keep ("Other time windows") stays offered
while it is the stored value.
4. A load locks every locked value again.
5. at_zero() needs an accepted 0 W write; before the first one Home says
"Going to 0 W" (the heartbeat writes every heartbeat_s, so it clears).
6. A field with a unit drops the translation's "(W)" from its label: the
peak limit read "Peak limit (W)" beside a kW value.
7. A mirrored choice lists the mirrored field's keys, so a search for
static_profile finds the contract on a fixed-price site.
8. test_settings: a save refused by ui_to_options writes nothing.
