fix(generate_ha): Russian function words in identity + exact-identity outranks subset

Dogfooding the voice layer exposed two pairing defects: (1) _FUNC_WORDS had no
Russian entries, so 'вкл/выкл/цвет/яркость' polluted device identity and an RGBW
colour GA could not find its own switch; (2) subset identity matching let
'RGBW подсветка яркость' {zone, подсветка} grab 'камин подсветка' by subset and
its status by tie-break. Sibling pick and status_for_dpt now prefer EXACT
identity equality before subset fallback. 13/13 tests green.
