refactor: 집행개시 시그니처 전용 경로를 BT 일반 패턴 스텝으로 통합

- PatternStepType.ChargeWait 및 ChargeStepData 도입으로 충전/차단 판정을 일반 패턴 스텝으로 표현
- UsePatternByRoleAction에서 IsSignature 분기 완전 제거, 일반 패턴 경로로 통합
- BossCombatBehaviorContext에서 시그니처 전용 메서드 10개 이상 제거
- BossStaggerAction(신규): 충전 차단 성공 시 보스 경직 처리
- SignatureFailureEffectsAction(신규): 차단 실패 시 범위 피해/넉백/다운 적용
- RebuildDrogBehaviorAuthoringGraph에 시그니처 Sequence + outcomeBranch 구조 추가
- 집행개시 에셋 스텝 구성을 ChargeWait(3초) → Skill으로 변경
- BossHealthBarUI 시그니처 UI 비활성화, PlayerSkillDebugMenu 디버그 메서드 제거
