Update the chat-room list mapper as well.
getChatRoom() now uses getDisplayNickname(), but getChatRooms() still delegates direct-room names to TeamRecruitmentChatRoomListItemResponse.of. That mapper uses getNickname() for both roomName and counterpartNickname. A user without a configured nickname will still produce null in the chat-room list response. Change both mappings to use getDisplayNickname().

닉네임이 설정되지 않은 사용자가 포함된 채팅방 조회 시 nickname 필드가 null로 응답되고,
메시지 전송 시 500 에러가 발생하는 문제를 수정합니다.
User.nickname은 nullable 컬럼이지만 getNickname()을 직접 사용하여 null이 그대로 노출되거나
@notblank 제약 위반으로 persist 실패하는 버그입니다.

💬 참고 사항
User.getDisplayNickname()은 nickname → anonymousNickname → "익명 사용자" 순으로 fallback 처리합니다.
