fix: SaveModal을 ResizableDialog로 수정하여 크기 조절 가능하도록 개선

주요 변경사항:
- Dialog/DialogContent를 ResizableDialog/ResizableDialogContent로 변경
- DialogTitle을 ResizableDialogTitle로 변경
- 내부 컨텐츠 컨테이너를 유연한 크기(w-full h-full)로 변경
- minWidth/minHeight 사용으로 최소 크기 보장

참고:
- 컴포넌트 레이아웃이 화면관리에서 설정된 대로 정확히 렌더링됨
- 레이아웃 자체의 문제는 화면관리에서 재설계 필요
