feat(mastervega): add morale bonus system and espionage restraint diplomacy

- Add morale bonus from buildings (e.g., Holo Simulator): flat +N% to total
  colony production, uniformly boosting construction, defense, industry,
  ecology, and research
- Add espionage restraint (offDrift): setting Intelligence to 'off' toward
  an empire with neutral-or-better opinion drifts their attitude upward by
  1/turn, giving a way to improve relations without gifting (gated on not
  being at war and their opinion of you being >= 0)
- Display morale bonus in colony view when applicable
- Reduce planetShotDamageMult from 10 to 6
- Add verification tests for both new mechanics
