Convert EndPleaseRecruitMePhaseAction to Scala GameState and fix test

- Convert EndPleaseRecruitMePhaseAction to take Scala GameState directly
- Rewrite EndDefenseDecisionPhaseActionTest to use pure Scala model objects
  (instead of creating proto GameState and converting)
- Fix test to expect correct phase transition (TruceTurnBack, not BattleRequest)
- Update BUILD.bazel deps for both action and test
