fix: open target panel when toggling Docked Job History (#9215)

## Summary
Make the Docked Job History toggle deterministic so it opens the
expected UI target in both directions.

## Changes
- Update `JobHistoryActionsMenu` toggle behavior:
- When currently docked (`Comfy.Queue.QPOV2=true`), disable docked mode
and explicitly open floating QPO (`Comfy.Queue.History.Expanded=true`)
- When currently floating (`Comfy.Queue.QPOV2=false`), enable docked
mode and open the `job-history` sidebar tab
- Add/adjust unit tests in `QueueOverlayHeader.test.ts` to verify both
toggle directions and target panel behavior

## Testing
- `pnpm exec eslint src/components/queue/JobHistoryActionsMenu.vue
src/components/queue/QueueOverlayHeader.test.ts`
- `pnpm typecheck`
- `pnpm test:unit -- src/components/queue/QueueOverlayHeader.test.ts`
