feat: 보스 패턴 페이즈 제한을 애셋 기반 minPhase로 통합

- BossPatternData에 minPhase 필드 추가 (기본값 1, Inspector 설정 가능)
- BossCombatBehaviorContext의 signatureMinPhase를 minPhase로 대체
- IsPatternReady와 CheckPatternReadyActionBase에 Phase 체크 통합
- BT 경로와 Update 경로 모두 일관되게 Phase 제한 적용
- 집행개시 패턴 minPhase=3, 점프 패턴 minPhase=2 설정
