A serial the account does not list is still a serial worth showing

The dropdown could only show a serial it had an option for. A remembered one the
account does not report — a charger imported before the account was linked, one
the cloud is quiet about today — selected nothing, so the field sat blank while
that serial was the one every command went to. Nothing on screen said which
charger was being driven, or let it be corrected.

The field now falls back to the text box in that case, the way it already does
when the account lists no chargers at all, and shows the serial actually in
force. One link switches between picking and typing, so a serial off the list is
not a dead end and the list is not the only way in; coming back to it lands on a
charger the list holds rather than blanking the dropdown again.

Which of the two is showing is decided when the list arrives, not on every
keystroke — recomputing it as the serial is typed would turn the text box into a
dropdown mid-word, the moment what had been typed happened to match.
