- Fix a real bug: airconditioner.SOUND_MODE had no exists_fn, so on
boards (issue #319's FAC) that never report a live 'mode' value,
entity.py's default field-presence gate silently kept the select from
ever registering in HA -- while adapter.flatten() (what the golden/tests
read) has no such gate, so the tests passed while documenting behavior
the opposite of what shipped. Gate on supportedModes' presence instead.
- Add airconditioner.MDS_ABSENCE_CLEAN for the CAC-class board's
/mds/absenceclean/vs/0 -- byte-identical shape to issue #319's
/csi/absenceclean/vs/0, confirmed rather than guessed, closing one more
of that board's documented coverage-gap hrefs.
- Add missing translation state labels (all 6 languages) for
edge_lighting_mode/edge_lighting_color/indicator_light_mode's raw device
codes, so they render as real words instead of a raw '3000K' -> '3000 K'
fallback.
- Fix an orphaned comment above SOUND_MODE that actually described the
unrelated DISPLAY reuse, and correct two inaccurate rationale comments:
the sound/voice ignore reason claimed a distinction from SOUND_MODE that
this same dump contradicts, and the /csi/* ignore block's 'same
reasoning as air_purifier.COVERAGE' precedent only actually covers 1 of
its 5 hrefs.
- Correct the false 'no board-token match' claim in the FAC test file and
golden-regression docstring -- 'FAC' is a real _BOARD_TOKEN_TO_KEY entry
(for_device_by_model alone already resolves this board); add a test
that actually exercises that path, which nothing previously did despite
the docstring's claim.
- Drop a tautological burner-slot test that only re-asserted what the
golden regression test already covers via the same code path.
