Summary by cubic

Keep Assistant/Org and Mode listboxes open until the user clicks outside; adds a shared useClickOutside hook to control closing behavior. Resolves CON-3879.

• Bug Fixes
  • Added useClickOutside to close listboxes only on outside clicks.
  • Made ListboxOptions controlled via listboxOpen + static and refs; removed programmatic Escape close.
  • Removed onClose props and stop closing on option selection; buttons now open the listbox, and it closes only on outside click.
  • Updated navigation/actions (e.g., New Assistant, Rules) to explicitly close the listbox after handling.

@uinstinct I think the current goal based on linear ticket is to keep the listbox open when you select an assistant
