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().

In
`@src/main/java/in/koreatech/koin/domain/teamrecruitment/service/TeamRecruitmentChatService.java`
at line 151, Update the chat-room list mapping in
TeamRecruitmentChatService.getChatRooms and
TeamRecruitmentChatRoomListItemResponse.of to use each user’s
getDisplayNickname() for both roomName and counterpartNickname, preserving the
existing mapping structure.
