Annotate auto assist in InitialAutoMode and SetAutoMode

[lL1l1]

Testing done on the proposed changes

• Toggling off InitialAutoMode for hives disables their automatic assistance. Weirdly enough the production toggle on hives doesn't actually toggle auto mode (through SetAutoMode), but it toggles whether auto mode can act or not.
• Toggling off InitialAutoMode for drones and the base station simultaneously toggles off automatic assistance.
• It's already known that auto mode toggles automatic silo building.

Other

I'm not sure what the exact requirements for a unit to be able to automatically assist are. The unit also only auto assists within its GuardScanRadius. The ENGINEERSTATION STATIONASSISTPOD PODSTAGINGPLATFORM categories seem important. Mainly STATIONASSISTPOD since it is on kennel drones and hives.
