UI 마감 튜닝: 권한 팝업 가독성·컴포저 밀도·점검 체크리스트 반영

- ChatWindow 권한 팝업의 섹션/행 패딩·폰트·줄간격을 미세 조정해 스캔 속도 개선
- 슬래시 팔레트 하단 안내에 PgUp/PgDn/Home/End 키 이동 정보를 반영
- 좌측 기본 카테고리 라벨을 주제 선택/작업 선택으로 통일
- 입력 상단 컴포저(모델/프리셋/인라인 설정) 간격을 컴팩트하게 재정돈
- docs/UI_UX_CHECKLIST.md에 최신 점검 결과(운영모드 필터 18건, 전체 테스트 436건) 기록
- README.md, docs/DEVELOPMENT.md 이력 및 업데이트 시각(2026-04-04 12:33 KST) 갱신
- 빌드 복구 메모: WPF 임시 생성물 꼬임 발생 시 obj/bin 정리 후 정상 재생성 확인
