AX Agent 작업 유형 카드 정리 및 hover 설명 라벨 적용

- 작업 유형 카드 하단 상시 설명을 제거하고 모든 카드 크기를 동일 규격으로 통일함
- 카드 hover 시 확대 애니메이션을 제거하고 하단 설명 라벨과 배경/테두리 반응만 남겨 안정적으로 정리함
- 기타/프리셋 추가 카드도 같은 hover 규칙과 설명 노출 방식으로 통일함
- EmptyState 제목/설명 폰트를 키워 현재 화면 전반의 글자 크기를 보정함
- README 및 DEVELOPMENT 문서에 2026-04-05 19:02 (KST) 기준 변경 이력을 반영함
