fix: Hide Menu if empty & render columns without state change

- 'Refresh' btn is always present in dropdown menu. Show menu if any other action is also present.
- Without `update_order` state is not changed, and thus columns are not rendered on `init()`
- If we are not updating order in the db, render columns with whatever information we have currently
