권한 팝업 밀도/정렬 미세조정: 핵심 모드 스캔 속도 개선

- 권한 행 패딩/마진, 아이콘/체크마크 간격, 제목/설명 타이포를 컴팩트하게 재정렬\n- 요약 카드 제목/본문 폰트 및 여백을 축소해 기본 화면에서 핵심 모드 가시성을 강화\n- claw-code 스타일의 빠른 스캔 밀도에 맞춰 권한 팝업 가독성/선택 동선을 보강\n- 문서 동기화: README.md, docs/DEVELOPMENT.md에 2026-04-04 16:58(KST) 이력 반영\n- 검증: dotnet build 경고0/오류0, dotnet test 필터 65 passed
