feat(control-pane): interactive JIT board — claim/move cards from the webapp

The board was read-only; you can now drive the agent+human JIT workflow from the local control pane. - New shared scripts/lib/control-pane/work-item-mutations.js (claimWorkItem, moveWorkItem) so the CLI and server never diverge; work-items.js claim now delegates to it. - server.js: gated POST /api/work-items/:id/claim and /:id/move (localhost-only, honors --read-only with 403). Claim sets owner + assigneeKind and moves to running; move retargets the kanban lane. - ui.js: per-card Claim (on unassigned cards) + lane buttons that POST and refresh; 15s live auto-refresh (paused when the tab is hidden). - Tests: interactive claim/move endpoints, read-only 403, invalid-lane 400, and snapshot reflects mutations. Full suite 2845/2845; lint green.
