feat v1.22.0: presence ripples, per-device icon size/rotation, one-click HACS badge

Visuals borrowed from easy-floorplan (github.com/nicosandller/easy-floorplan), model kept ours.
isActiveState is independent of the live_states toggle; unavailable/unknown count as idle.
Honours prefers-reduced-motion. Badges scale with --dev-size. +1 test (74).
