feat(635-5): B05 경위도 ↔ 사업지 좌표 서버 변환 길 · 찾기 이동 정확 · 속성 판 경위도(요구 546)

- POST /api/projects/{id}/route/coords — 작업 좌표계(resolve_project_crs · WKT 그대로) pyproj 묶음 변환
- 찾기 이동 = 서버 변환 좌표 · 바탕 tm_grid 늘려 쓰기(ponytail) 걷음
- 키트 lonLat = 노드 고를 때 한 번 묻기 · 같은 점 캐시
- test_635_3 찾기 줄 = 서버 변환 부름으로 고침(옛 tm_grid 부름 걷힘)
- 실측 검증_sub6 B: 50.4 km · 181.2 km 찾기 이동 어긋남 0.000 m · 경위도 = pyproj
