feat(k3): align RIT/XIT and the power step with the other consoles

'None of the consoles look alike' is the complaint ShiftRow exists to answer,
and the Elecraft panel was still driving its offset with a row of nudge buttons.
It now uses the shared control — ±, wheel, typed value — plus the same
Ctrl+←/→ 10 Hz clarifier the Icom and TCI panels have. The K3 keeps ONE offset
for RIT and XIT, so both rows show it, exactly like the Icom's.

The backend gains the absolute setter the shared control speaks
(SetKenwoodRITOffset, funnelled through the same RO write as the nudge), and
the power slider moves in 1 W steps — nobody asks a K3 for 'between 10 and 15
watts' in fives.

Also per review: the chase switches are labelled 'Chase POTA' / 'Chase SOTA',
matching 'Chase new grids' beside them.
