edit: some observations.
Freezing empire size only seems to help for research costs. To get a hold onto the leader upkeep that'll eat a huge chunk of energy I had to come up with a different solution.
I ended up setting tech_repeatable_improved_core_system_cap sufficiently high, which is still an ugly hack but kind of works for both tech and leader upkeep costs.
However I have absolutely no clue how to get the edict cost values under control.
