Addresses "the list on every page isn't good": adopt the approved mockup's
card design (icon well, name, sub, live state chips, footer toggle).
- New <x-device-card>: per-device card with online dot, cloud badge, entity
chips and an inline switch/light toggle (active cards highlighted accent).
- TogglesEntities trait → dashboard, devices index, rooms show all drive the
same toggle (H1, audited); card grids replace the divide-y rows.
- Dashboard + devices grouped into responsive card grids by room.
- Windows page: sensor cards showing closed/open/tilted prominently, low-battery
chip, open sensors highlighted (screenshot-verified).
- Rooms index already card-based; left as-is.
Suite 51 green, 12/12 tabs clean, zero console errors.
