Closes the coverage-gap repair for two more room-AC boards (issues #37,
- TP2X_RAC_20K reports no oneUiVersion and no '_PRAC_' modelNum token, so
its device type went unrecognized -- add a '_RAC_' fallback token to
for_device_by_model.
- Bind the resources both dumps actually populate: mute-once (switch),
display light (switch), self-check (reused from fridge.SELF_CHECK), and
the circuit-breaker current-limit setting (read-only diagnostic sensors,
since its write contract isn't confirmed from the dump).
- Ignore the rest as plumbing/opaque/unconfirmed: control-set descriptor,
keepnormalstate flag, software-reset trigger, AI Sleep handshake,
absence-monitoring stubs, remote-data-control, remote-temperature,
reservation ruleset, and the welcome-temperature tracker.
Adds scrubbed fixtures + goldens for both dumps and extends the AC
capability/golden-regression tests to assert zero unbound hrefs.
