## Context
Realised that MultiSelector's content is not scrollable when rendered
within a sheet (e.g Auth policies, Database indexes)
### Explanation from Claude:
- The issue is that Radix Dialog (Sheet) adds
@radix-ui/react-remove-scroll which intercepts wheel events. The Popover
portal renders outside the Sheet's DOM tree, so the scroll lock blocks
wheel events on CommandList.
- The fix is to stop wheel event propagation on the CommandList so it
doesn't reach the RemoveScroll handler.
### To test
- [ ] Verify that MultiSelector can be scrollable within a sheet (e.g
Auth policies roles) and outside of a sheet (e.g Data API -> Exposed
schemas)
