feat(card): the LED strip tool in the Devices editor (#780)

Stage 4 of #780 (ТЗ §4–§5). «LED strip» next to «Add» draws a chain with
clean clicks only (pan, pinch, a second finger, cancel and the synthetic
click after navigation add nothing), snaps to the grid and to physical wall
faces / zero-wall axes, stops at the first face of masonry, partitions,
columns and windows (doors, gates and passages are cut by geometry), Shift
gives 45°. Ctrl+Z removes the chain's own point first, Esc finishes, a
double click or a click on the first point (≥3 vertices) closes; fewer than
two distinct points write nothing. A finished strip opens the device picker
(lights first, taken markers explained, «New device…» binds in that
dialog's own write, «Later» keeps unbound geometry).

A selected strip shows its vertex handles (a drag re-checks both neighbours
and the whole path) and a new Devices tray branch: device settings,
bind/change, unbind, show as icon, delete. The device dialog gets the
representation section: show as strip (restores a hidden shape at once or
draws one for this marker, behind the dialog's own save/discard guard),
show as icon, unbind/delete for a hidden shape. Every geometry or
representation change is one optimistic write and one LED command of the
device history; Undo/Redo restores only its own strip record and refuses
when a newer change sits on it. A rebinding renames the link in the marker
save, a deleted marker leaves an unbound strip, a bound marker may not move
to another space. Plan/Background show strips as a passive translucent mark.

The tool, its `led` dictionary (en static, ru/de/fr lazy) and placement
geometry are a new lazy `led-strip-editor` chunk (9.5 KB gzip), loaded only
on the tool, an editable strip in the shown space or a strip device's
dialog. The initial graph gets the loader and delegation only
(src/led-strip-card.ts); the lazy editor graph +122 B, inside its ceiling.
Mutant anchors follow the moved code (marker dialog guard, static LED layer).
