feat(roof-shape): PDF 지붕형상 매칭 버튼 자동 선택(pre-select)

[작업내용] :
- 마운트 시 pdfRoofShapeDescriptorState → matchRoofShapePattern → setShapeNum(매칭 버튼 pre-select)
- pre-select only: handleSave 비자동(사용자 [적용])
- consume-once: 매칭 시도 후 atom 리셋(비-PDF 재진입 stale 방지)
- 매처 null(복합형) 시 강제 선택 없이 기본값 유지
- 런타임(실제 분기별 pre-select) 수동 검증 잔여
