SAI Editor: Re-Organize Smart Events and Smart Action selection in categories instead of numerical order

Start by locating the SmartAI event, action, and target selection entry points in the editor and inspect how their numerical ordering is built. Group the available choices under the categories described in the issue, and consider the work complete when all three selectors present those categories rather than index order.
