Add Pinned Management Section and UI Polish

[pokocat]

**Motivation** Pinned items are a user's curated shortlist. Giving them a dedicated area and an easy way to reorder or unpin them makes day-to-day use faster and more intuitive. Persisting the pinned order removes the frustration of reordering after every app relaunch. The UI tweaks keep the numeric shortcut badges readable and add a convenient Pin action to normal history items without cluttering the interface. **Changes**

• New PinnedSectionView at the top of the popup:

Shows a "Pinned" header with a "Manage"/"Done" toggle.
In manage mode, each pinned item exposes "Unpin" and "Move Up"/"Move Down" controls.
Adds a divider between pinned and unpinned lists when there’s no search query and both sections are present.

• Stable pinned order persistence:

Defaults.pinnedOrder stores the user-defined pin order.
Sorter.sort now respects Defaults.pinnedOrder when assembling the list, honoring the user's pins position preference.
History.togglePin updates Defaults.pinnedOrder on pin/unpin actions; History.movePinnedUp/Down adjusts the order and persists it.

• UI Refinements:

Increased the trailing padding of pinned item management controls to prevent them from overlapping with the right-side shortcut badges.
Added a hover-only quick "Pin" button on the right side of unpinned items.
When numeric shortcut badges are present, a thin separator is inserted to visually distinguish them from the new "Pin" action.

@pokocat Nice feature and idea to manually sort the pins. I do have a couple of enhancement ideas that I'd like you to consider:

• Include a shortcut to move the pinned items up / down, e.g., using the arrow keys / drag and drop via mouse in managed mode. I find clicking the up / down arrows using the mouse to be somewhat cumbersome, especially if one has a lot of pinned items as I do
• I've attempted to allow sorting via Pin Keys (check PR Pins sorting logic for popup and panels #1263 ). Could you integrate the automatic and manual sorting logic, please?

Thanks for this cool feature!

PS: I've updated the PR with a (hopefully) better implementation of the sorting logic

@pokocat This is really cool, thank you for sharing this PR and working on it. I would like to see if we can push it even further and implement a drag-and-drop operation on the history items. This way, we won't even need to implement a separate "Manage" mode because users can click on the item, drag it to the position they want, and this would update the order.

To add my 2 cents: an option to move the items via keyboard, say via Control / Option key. That would be awesome!

good advise! but I noticed that there're already hover event on each item, I have to find a way to do so. But I’ve got my hands full at the moment, I'll continue working on it later..

@pokocat Please take a look at #1263 and #1265 (needs fixing, but you might want to check whether you could re-use some code / logic from this PR). The issue with #1265 is that there's a conflict between automatic and manual sorting that I haven't managed to fix yet, but hopefully, you have a head start here.
