Refine ranking placement, visibility, and consistency

- Move cumulative ranking above the gold ₩1M card (ranking → challenge flow)
- Drop redundant "전체 보기" link (inline folding shows full Top 10);
  /leaderboard route kept for direct access
- Make fold toggle purple + match its size to the tab buttons; enlarge
  title/tab/row text for readability
- Match email input & submit button radius to the ranking box (rounded-xl)
- Leaderboard full page: top button = "투표로 돌아가기" (history back, home fallback)
