Fix wall oven device-type detection (issue #55)

Ovens with modelNum like TP1X_DA-KS-OVEN-0107X report no oneUiVersion
and don't match any consumer-prefix or other fallback token in
for_device_by_model, so the device came back as "unknown" and every
resource fell through to the global capability registry instead of
oven.py's own -- explaining the unbound /connected/vs/0 href, the
unrelated-looking entities, and the non-functional controls reported
in the issue. Add a '-OVEN-' modelNum token fallback, mirroring the
existing '-RANGE-' fallback from issue #44.
