## Summary
Add sidebar badge behavior for queue/asset visibility updates:
- Job History tab icon shows active jobs count (`queued + running`) only
when the Job History panel is closed.
- Assets tab icon no longer mirrors active jobs; when QPO V2 is enabled
it now shows the number of assets added since the last time Assets was
opened.
- Opening Assets clears the unseen added-assets badge count.
## Changes
- Added `iconBadge` logic to Job History sidebar tab.
- Replaced Assets sidebar badge source with new unseen-assets counter
logic.
- Added `assetsSidebarBadgeStore` to track unseen asset additions from
history updates and reset on Assets open.
- Added/updated unit tests for both sidebar tab composables and the new
store behavior.

## 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.
