fix(highlight): settings UI fixes from review — grouped view, import guard, basic flag

- grouped view actually clusters: drop the priority column's defaultSortOrder
  that made antd re-sort the dataSource and undo the category clustering
- replace import is Popconfirm-guarded and the import mode resets to append
  each time the dialog opens (it stayed on the destructive choice)
- rule editor exposes the basic flag (basic-mode membership) with a switch;
  clearing it on edit now actually removes the flag
- rule/profile writes read the store at call time instead of the render-scoped
  array, so two writes in one React batch no longer drop the first
- profile editor lists the rules a non-empty profile leaves out (uses the
  previously dead excludedByProfile helper)
- bands editor keeps rows sorted by min; band preview keys by index (duplicate
  min no longer collides); clear-background also closes the bg picker
- TerminalView pushes compiled rules into the HighlightStream from an effect
  instead of during render
