Route combi microwaves onto the existing oven registry (issue #121)

TP1X_DA-KS-MICROWAVE-01041 (MW7300B) reports no oneUiVersion and an
unrecognized consumer token, so it fell back to 'unknown' and only got
common capabilities. It shares the same '/oven/vs/0' cavity resource
and '/mode/vs/0' cook-mode shape (Convection/AirFryer/Grill/MicroWave*)
as the wall oven already supported, so this reuses that registry via a
new '-MICROWAVE-' modelNum fallback rather than adding a new device
type. The only href it didn't already cover was /recipe/cook/vs/0, an
empty quick-recipe-display blob bound with no entity per the 'don't
guess' rule.
