fix: a cold View survives a telemetry-bearing vacuum (#358)

Systematic audit after #357 ("can there be more bugs with this root
cause?"): _vacMapId was the one remaining hard stub reachable from the
eager View path. It runs inside willUpdate for every vacuum whose
integration reports live telemetry (Tasshack, XCME, Valetudo), so on a
cold tab the #337 stub threw there and the exception took the whole Lit
update cycle with it — the card froze on its very first frame. The demo
mower has no position attributes, telemetry resolved to null, and every
existing smoke (warm and cold) sailed past the branch.

The card now owns the implementation (both dependencies — _vacEntity and
vacMapIdWithFallback — were already eager); the editor runtime delegates
back to the host. The HP-1541-01 invariant (selected_map: 0 is a real map
id, nullish not truthy) moves verbatim and is pinned by the new smoke.

Hardened alongside (audit Lows): _decorShapeDown gets the same
cold-tab guard its twin _decorShapeDbl received in #337 — decor shapes
render in View and CSS pointer-events alone must not be what prevents a
throw; the _vacCalConfirm dialog renders behind the same _editorRuntime
gate as every other editor dialog instead of relying on the implicit
"only the runtime ever sets it".

smoke_cold_view_vacuum: cold tab, vacuum with vacuum_position and
selected_map: 0 — the card commits three successive telemetry frames
(willUpdate alive, not merely the first paint), map id resolves to '0',
no editor chunk requested, a decor pointerdown is a quiet no-op. A
registry mutant restores the delegation and is killed by that smoke.

Issue: #358

 ## Unreleased
 
+- A robot vacuum that reports its live position no longer freezes the card
+  on a freshly opened page: the map-id lookup ran inside the render cycle
+  and required editor code that a cold tab has not loaded yet, so the very
+  first frame was also the last one
+  ([#358](https://github.com/Matysh/houseplan-card/issues/358)).
+
 - Tapping a device on a freshly opened page works again without first
   visiting any editor screen. A wall switch controlling virtual light sources
   (and every other tap-to-toggle device) silently ignored the tap on a cold
