Pointer-based drag layer for the advanced condition builder - a carry clone that follows the pointer, drop indicators between rows and into groups, and Alt to copy.

Add the "Pointer-based drag layer for the advanced condition builder - a carry clone that follows the pointer, drop indicators between rows and into groups, and Alt to copy." component (reui/filters-dnd, from ReUI) to this project.

1. Run: npx get-ui-cli add reui/filters-dnd --yes
2. Read the "Use it" snippet it prints, then import the component and render it where it fits.
3. Don't rewrite the installed file. Adapt it through its props and className, so `npx get-ui-cli update` can still merge upstream fixes.
4. Run: npx get-ui-cli doctor, and fix anything it reports.
