wired-tools: hoist variable-highlight toggle + overlays to the store

Move the highlight feature pair into useWiredCreatorToolsUiStore:
isVariableHighlightActive (toggle UI flag) and variableHighlightOverlays
(computed screen-space overlay positions). The two screen-coords effects
in WiredCreatorToolsView stay where they are (they need React's
lifecycle to install / tear down WiredSelectionVisualizer highlights on
the active room objects) but now write to setVariableHighlightOverlays.

WiredVariablesTabView drops the isVariableHighlightActive +
onToggleVariableHighlight props and consumes the store directly — same
shape as the previous tab-prop reductions on this branch. The toggle
button keeps the same UX (Highlight ↔ Undo) but no longer crosses the
prop boundary.

Direct benefit: closing and reopening the panel while a variable
highlight is active no longer flickers the overlays off and back on —
the active flag + the last-computed overlay set both persist in
zustand and the effect re-runs from the same starting point.

Tests: three new cases on the store (toggle via direct + updater,
overlay replace + clear, close/reopen persistence). 190/190 passing.

variableHighlightObjectsRef stays a useRef inside the component: it
tracks the live PIXI objects WiredSelectionVisualizer drew onto, used
only for the cleanup pass — refs don't trigger renders and don't need
to live in the store.
