fix(lobby): 플레이테스트 — 이동 복원에 InputSpeed 필수 + FixedLookAt int 타입 (P15)

메이커 실측으로 확인:
- 이동에는 RigidbodyComponent.WalkAcceleration과 MovementComponent.InputSpeed가 둘 다 양수여야 함(WalkAccel만으론 안 걸림). LobbyMobility에 InputSpeed=5·JumpForce=5 추가.
- pc.FixedLookAt은 boolean이 아니라 int32 → false→0 (빌드 에러 해소).
- PlayerLock에 InputSpeed/JumpForce=0 대칭 재잠금 추가(전투맵 누설 방어).
- NPC 베이스 모델 inheritance 경고는 비치명적이라 proven-good(모델 유지) 결정 주석화.

검증: 로비 이동·점프, NpcCodex 근접(d=1.10<1.2)·↑키→카드 도감, 런 시작→map01 텔레포트+이동 잠금(InputSpeed=0), 로비 복귀→이동 재해제 전부 정상.
