"Can they launch units?"

Yes.

"For that matter, can a rioting planet execute any order?"

Yes, there are some orders they can issue.

"Will a spaceyard on a rioting planet repair ships in the same sector?"

Not sure.

"What happens when something in the build queue that is partially completed, the planet riots, then stops rioting? Does the queue continue where it left off or does it get reset?"

It should continue where it left off.

"Do system-wide facilites on rioting planets still work?"

Yes.

"Do training facilites work?"

I would assume so.

"Do planet modification facilities (value improvement, climate, atmosphere converters) work?"

No idea.

"What about planetary shield generators? Or system shield generators?"

System shield generators are system wide abilities, so yes. I think planetary shield generators should still work.

"I don't use them, but what about recycling facilites?"

They are system facilities, so probably.

"Will Weapon Platforms work during combat?"

Yes.

"Will the rioting planet launch fighters or drones in combat?"

Yes.

"Will the rioting planet produce militia against dropped enemy troops?"

Yes.
