feat: 게시판 추천/비추천 + 작성자 아바타 + 추천자 + 활동 포인트

- 작성자 아바타: post/comment 조회 시 member JOIN(google_picture/profile_image),
  목록·상세·댓글 응답에 노출
- 추천/비추천: post_vote/comment_vote 테이블 + 토글 API
  (POST /board/posts|comments/{id}/vote), 게시글/댓글 응답에 up/down/myVote
- 추천자 목록: GET /board/posts/{id}/recommenders + PostDetail.recommenders
- 포인트: member.points + point_history. 글/댓글 작성 시 10P, 하루 3회 한도(합산).
  PointService, GET /auth/points, MemberResponse.points 노출
- @MapperScan 에 point.mapper 추가, AuthController WebMvc 테스트 MockBean 보강
