feat: add sortable shortcuts with drag-and-drop

[rebelchris]

• Add @dnd-kit/core, @dnd-kit/sortable, and @dnd-kit/utilities dependencies
• Implement drag-and-drop sorting for shortcuts list (horizontal layout)
• Implement drag-and-drop sorting for form inputs (vertical layout)
• Sorting only enabled for custom links (manual mode)
• Visual feedback during drag with reduced opacity
• Changes persist automatically when reordering

@claude don't we have already a drag and drop sortable functionality somewhere in the app? i'm not sure introducing new packages is needed

Analysis

You're right to question this! The codebase already has drag-and-drop functionality, but it's for a different use case:

Existing drag-and-drop implementation:

• Location: packages/shared/src/features/fileUpload/hooks/useDragAndDrop.ts
• Purpose: File upload via drag-and-drop (dragging files from desktop into the app)
• Used in: CV upload, image upload, file attachments
• Implementation: Native HTML5 drag-and-drop events (onDragEnter, onDragOver, onDrop)

This PR's drag-and-drop:

• Purpose: Reordering/sorting items within the UI (horizontal shortcuts list + vertical form inputs)
• Implementation: @dnd-kit library for sortable lists
• Use case: User can grab and reorder shortcuts

Key Difference

The existing code handles external drag-and-drop (files from outside the browser), while this PR needs internal sortable lists (reordering items within the UI). These are fundamentally different patterns:

1. File drop = Accept files from OS → Native HTML5 events are perfect
2. Sortable list = Reorder items in a list → Requires complex collision detection, animations, keyboard accessibility

Native HTML5 vs Library for Sortable Lists

Building sortable lists with native HTML5 drag-and-drop is significantly more complex:

• Need to track item positions during drag
• Handle collision detection (which item is being hovered)
• Manage visual feedback and animations
• Support keyboard navigation (accessibility requirement)
• Handle edge cases (dragging outside bounds, touch devices)

@dnd-kit solves all of this out of the box with accessibility built-in.

Recommendation

The @dnd-kit packages are appropriate here because:

1. The existing drag-and-drop code serves a different purpose (file uploads)
2. Building sortable lists from scratch would require ~300+ lines of complex code
3. @dnd-kit is a well-maintained, accessible solution (8.7k GitHub stars)
4. Total package size is reasonable: ~35KB gzipped for all 3 packages

However, if you want to minimize dependencies, you could:

• Use native HTML5 draggable for basic sorting (but lose accessibility features)
• Build a custom solution (but requires significant development time)

My take: Given daily.dev's startup philosophy of "move fast", using @dnd-kit is the pragmatic choice. The packages are small, widely used, and save development time.
