ProjectMemberService 의 notify payload 에 actorName 이 빠져 있어, 프론트
notification.store 가 actorName 부재 시 '누군가'로 폴백하던 문제.
세 member.* 알림(invited/role_changed/removed) payload 에 actorName 추가
(actingUserId 로 사용자명 조회하는 actorName 헬퍼 신설). 활동 피드는 actor
관계로 별도 해결되므로 영향 없음.

런타임 검증: 초대 시 수신자 알림 payload.actorName = 초대자 이름으로 채워짐.
백엔드 build/lint 0·8 tests.
