feat(site-finder): P1 geometry suitability score (#45)
Backend (parcels.py): - _polygon_suitability() — Shapely metrics on parcel WGS84 polygon: area_ha/m2 (projected via cos(lat) к UTM-like meters), perimeter_m, aspect_ratio (long/short side of MABR), convex_hull_ratio (area / hull area), min_inscribed_rect_dim_m. - Composite suitability score 0..1: base = area_subscore (0 при <0.2 ha, linear → 1 при ≥0.5 ha) −0.3 если aspect_ratio > 5 (вытянутый) −0.3 если convex_hull_ratio < 0.65 (изрезанный) −0.5 если min_inscribed_rect_dim_m < 30 (узкий) - Label: микро / подходящий / сложная форма / слабо подходит - Recommendation: "для МКД 16+ нужно >0.3 ha + минимум 40м" - В analyze response → geometry_suitability. Frontend: - Новый GeometrySuitabilityBlock.tsx с color-coded badge + метрики grid + penalties + recommendation - Добавлен в LandTab (выше "Зонирование (ПЗЗ)") - TS типы расширены: GeometrySuitability Closes #45.
