wired-tools(store): hoist variable-key records (selectedInspectionVariableKeys, selectedVariableKeys)

Move the last two `Record<...Type, string>` useStates out of
WiredCreatorToolsView into useWiredCreatorToolsUiStore. Both writers
were already using the `prev => ({ ...prev, [key]: value })` updater
shape, so the new store setters expose `Updater<Record<...>>` to keep
existing call sites verbatim.

Initial values default to empty strings; the existing
`variableDefinitionsByType` sync effect at WiredCreatorToolsView.tsx
:1543-1574 already populates valid keys on first render and reconciles
whenever the server-side definitions change. Closing/reopening the panel
now preserves the active picker key instead of resetting it.

Tests: 4 new cases on the store (updater shape, single-key patch
preserving siblings, direct-record write path, panel-lifecycle
persistence). Suite: 197/197 (was 193/193).
