feat(furniture): nightstand legs, bookcase columns/drawers, AC unit LG style, soundbars, wood-cube sconce

- NIGHTSTAND: optional legs with adjustable height (capped at 60% of total height) - BOOKCASE: shelfColumns with vertical dividers, per-cell drawer fronts with handles, z-fighting fix between dividers and back panel, stale drawerCells pruned on grid shrink - AC_UNIT: new 'lg' style with dark vent, grille lines, deflector flap, LG accent - SPEAKER: new 'soundbar' variant (90/110/140cm) with grille, driver cones, LED strip; SpeakerMesh split into dispatcher + SpeakerCabinetMesh to keep hook order stable - Wall light: new 'wood-cube' style (wooden block sconce with top/bottom glow) - PropertiesPanel: tf() helper replaces repeated i18n.exists fallbacks; inline checkbox styles consolidated into styles.checkboxLabel - Translations: en/ru entries for new property keys
