feat: ж/д слой + cant_swim в скоринг + профили вне модели

Определение специфических рекомендаций (матрица профилей §8):

1. Ж/д слой (закрыт мёртвый railway ×2.5 у РАС):
   - /api/v1/water/{case_id} отдаёт railway=rail как LineString
     (без service/industrial/military веток), кэш общий v2;
   - railway_warning «перекрыть/проверить немедленно» по профилям;
   - SearchMap: Polyline слой ж/д (тёмно-красный), счётчики 💧/🚂.

2. cant_swim → профиль не_умеет_плавать (water ×3.0, без изменения
   радиуса, critical_warning «обследовать водоёмы НЕМЕДЛЕННО»):
   - раньше чекбокс влиял только на текст, в скоринге был пробел;
   - derive в analyze._derive_profiles — работает и для closed_cases.

3. unmodeled_profiles: ДЦП/слабое зрение/слух — честная пометка
   «вне поведенческой модели» с пояснением (vector_tasks B12:
   профили без аналога не выдавать за учтённые); блок на фронте
   в карточке здоровья.

Площадь воды: сферический эксцесс, проверен на квадрате 53° (744017 м²
vs 743272 точного). Тесты: 202 passed (новый test_cant_swim_profile).
