feat(mypage): hero 축소 + "구매한 팩" 탭 신설 + 빠른 메뉴 AI 스튜디오 추가

- Hero: bg-[#04102b] → kx-surface, py-10→py-8, 아바타 보라 액센트, 가입일 톤 다운,
  로그아웃 버튼 제거 (TopNav가 담당)
- Tab type에 'packs' 추가, 결제 내역 다음 위치에 "구매한 팩" 탭
- packOrders 계산: orders.service 에서 extractPackTier로 Music 팩만 필터
- 신규 탭 JSX: status별 분기(완료/처리중/대기) + 자료 리스트 + 비활성 다운로드 버튼
  + 카톡 안내. Phase 2에서 다운로드 활성화 예정
- 빠른 메뉴: AI 스튜디오 카드 1개 추가 (사주·외주 옆), grid-cols-2→sm:grid-cols-3
- 탭 컨테이너 flex-wrap 적용 (모바일 7개 wrap)
- handleLogout 함수 제거 (사용처 없어짐)
