feat: 코드 리뷰 기반 전면 개선 — 보안, 검증, 테스트, 안정성

- 체인 nonce 경쟁 조건 수정 (operatorMu + per-user mutex) - 등록/SSAFY 원자적 트랜잭션 (wallet+profile 롤백 보장) - IdempotencyRequired 미들웨어 (SETNX 원자적 클레임) - 런치 티켓 API (JWT URL 노출 방지) - HttpOnly 쿠키 refresh token - SSAFY OAuth state 파라미터 (CSRF 방지) - Refresh 시 DB 조회로 최신 role 사용 - 공지사항/유저목록 페이지네이션 - BodyLimit 미들웨어 (1MB, upload 제외) - 입력 검증 강화 (닉네임, 게임데이터, 공지 길이) - 에러 메시지 내부 정보 노출 방지 - io.LimitReader (RPC 10MB, SSAFY 1MB) - RequestID 비출력 문자 제거 - 단위 테스트 (auth 11, announcement 9, bossraid 16) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
