Addresses "I arrange tiles but nothing changes":
- Demo devices have no hardware to echo a new state, so toggling looked dead.
DeviceCommandService now simulates that echo for demo devices (writes the new
state + broadcasts DeviceStateChanged) — the mock home is fully interactive
(handoff §13.2). Real devices are untouched; their own status message applies.
- Panel tiles show the entity name (device · room as sub) and drive the shared
TogglesEntities toggle; wire:loading guards double-taps.
- Drag-reorder now confirms with a "Layout saved" cue so it doesn't feel inert.
+1 test (demo toggle simulates echo; real device does not). Browser-verified:
tapping an "Aus" tile flips it to "An". Suite 52 green, 12/12 clean.

New "Steuerung" page for tablet control:
- Large touch tiles for every light/switch — tap toggles (through
DeviceCommandService), highlighted when on, live via Echo.
- Drag-to-reorder via SortableJS (handle per tile); order persisted to
entities.panel_sort.
- Lights get a colour/brightness modal → Light.Set (brightness + rgb) on the
Shelly, with preset swatches + a custom colour picker. Driver contract gains
setLight(); command service audits it (H1).
Nav check 11/11 tabs clean.
