fix(registry): route TP1X_DA-AC-CAC boards to airconditioner (#191)

The 0.16.0 device-type simplification dropped oneUiVersion detection on
the assumption every device it typed was already reachable via a modelNum
board token. Cassette AC units (TP1X_DA-AC-CAC-01001_0000) were the one
exception -- they only ever resolved through oneUiVersion's "Air
conditioner" string, since 'CAC' was never added to the board-token
table -- so they silently fell back to common caps and lost their
climate entity.
