wired-tools: hoist inline editor state (variables + managed holder) to the store

Move the four inline-editor useStates out of WiredCreatorToolsView and
into useWiredCreatorToolsUiStore:

- editingVariable / editingValue — Inspection-tab variables-table
  inline edit (current key being edited + in-flight input text).
- editingManagedHolderVariableId / editingManagedHolderValue — same
  pair for the Variable Manage panel's holder rows (id 0 = none).

WiredInspectionTabView drops three more props (editingVariable,
editingValue, onEditingValueChange) and consumes the store directly
for the read sides + the per-keystroke setEditingValue. The cancel /
keydown / begin handlers stay in the parent because they wrap
shouldPauseVariableSnapshotRefresh-aware logic plus selection
bookkeeping that doesn't belong to a pure tab body.

The shouldPauseVariableSnapshotRefresh derived flag still reads from
the same store now-backed values; no behaviour change on the polling
suppression path.

Tests: three new cases (set+read pair, null-clear, managed-holder
0-as-sentinel reset). 193/193 passing.
