feat(B01): 프로젝트 카드 요약 함수 · API — 단계 · 썸네일 선 · 담당 · 멈춘 날 · 연장 · 측점 · 구조물 (PLAN 547-1)

- B01_Dashboard_Summary.project_summaries(ids) — 쿼리 다섯 번(개수 무관) · 넣은 차례 · 없는 값은 칸 뺌
- 썸네일 = 최신 노선 GeoJSON 중심선 100 점 안쪽 · 0~1 칸(가로세로 비 유지 · y 아래로)
- GET /api/dashboard/projects/summary?ids= — 보이는 프로젝트만(시스템 관리자 전부 · 회사 · 내 것)
- 실측 21 개 0.14 s
