AX Agent UI/UX 동등 품질 정비: ChatWindow 테마 일관성 강화 및 컨텍스트 메뉴 커스텀 팝업 전환

- ChatWindow.xaml에서 hover/selected/상태 배지/토스트/입력 칩/파일 미리보기 영역의 하드코딩 색상을 DynamicResource 기반으로 정리해 Codex/claude-code 지향 테마 일관성 강화

- 상단/하단 상태 배지와 데이터그리드 시각 요소를 PrimaryText/AccentColor/HintBackground/BorderColor로 통일해 라이트·다크 전환 시 가독성 확보

- ChatWindow.xaml.cs에서 ContextMenu/MenuItem 기반 구현 제거, 공통 커스텀 Popup 메뉴 빌더(CreateThemedPopupMenu/CreatePopupMenuItem)로 최근 폴더/메시지 우클릭 메뉴를 통합

- 기본 MessageBox.Show 사용 경로를 CustomMessageBox.Show로 교체하여 지침 준수(메시지 삭제/파일 삭제 확인)

- 검증: dotnet build 경고 0 오류 0, dotnet test(371/371 통과)
