feat: PWA 세션 유지 자동적립 + 메타 태그 + 설치 유도 배너

- 세션 설정: 90일 유지, SameSite=Lax (QR 스캔 시 쿠키 전송)
- 적립 성공 시 세션에 유저 정보 저장 (3곳)
- /claim 자동적립: 세션에 유저가 있으면 입력 없이 바로 적립
- /logout 라우트 추가, 마이페이지 헤더에 로그아웃 버튼
- /sw.js, /privacy 라우트 추가
- 고객용 템플릿 6개에 PWA 메타 태그 + 서비스 워커 등록
- 적립 성공 화면에 PWA 설치 유도 배너 (iOS/Android 분기)
- session 변수명 충돌 수정 (db_session으로 변경)
