feat: split job history into a dedicated sidebar tab (#8957)

## Summary

Move queue job history into a dedicated sidebar tab (gated by `Comfy.Queue.QPOV2`) and remove mixed job-history UI from the Assets sidebar so assets and job controls are separated.

## Changes

- **What**:
  - Added `JobHistorySidebarTab` with reusable job UI primitives: `JobFilterTabs`, `JobFilterActions`, `JobAssetsList`, and shared `JobHistoryActionsMenu`.
  - Added reactive `job-history` tab registration in `sidebarTabStore`; prepends above Assets when `Comfy.Queue.QPOV2` is enabled and unregisters cleanly when disabled.
  - Added debounced search to `useJobList` (filters by job title, metadata, and prompt id).
  - Extracted clear-history dialog logic to `useQueueClearHistoryDialog` and reused it from queue overlay and job history tab.
  - Removed active-job rendering and queue-clear controls from assets list/grid/tab views; assets sidebar now focuses on media assets only.
  - Removed the QPOV2 gate from `MediaAssetViewModeToggle` and updated queue/job localized copy.
  - Added and updated tests for queue overlay header actions, job filters, search filtering, sidebar tab registration, and assets sidebar behavior.

## Review Focus

- Verify QPOV2 toggle behavior:
  - `Docked Job History` menu action toggles `Comfy.Queue.QPOV2`.
  - `job-history` tab insertion/removal order and active-tab reset on removal.
- Verify behavior split between tabs:
  - Job controls (cancel/delete/view/filter/search/clear history/clear queue) live in Job History.
  - Assets sidebar loading/empty states and list/grid rendering remain correct after removing active jobs.
