I was hoping to also to find a way an advanced empire could help a primitive power catch up in tech, but that seems to be absent.
If you haven't looked at them, there are a couple of treaty types in the campaign moderators guide which might help or give you a starting point.
The Research Treaty is one option which supports a yearly boost to the tech investment based on how much each partner invests. The other one (which may serve as a better starting point for what I think you are after) is the tribute treaty. As written it doesn't really cover the aid being sent to Grayson from Manticore, but it could probably be turned around and used as the basis of an economic aid treaty. There is likely a Naval Appropriation Treaty between them as well.
In addition, each of these treaties include some aspect of passing EP between states. In each case the treaty specifies the terms and amounts and then the transfers just happen. There is no requirement for a set amount of trade or transport fleets to support the transfer.
