Render the §12.1-13 geometry already exposed on /analyze but previously
dropped by the MiniMap adapter:
- Перспективные ЗУ (nspd_opportunity_parcels.geom_wkt) — viz-3 polygons
- Красные линии застройки (nspd_red_lines.geom_wkt) — warn dashed lines
Wired as toggles in the existing CpLayerControlPanel (Рынок group),
reusing wkt.ts (extended with LINESTRING/MULTILINESTRING for red lines).
Empty/invalid geometry renders nothing gracefully; popups RU plain-text.
§22 forecast (future_market/special_indices), ППТ-ПМТ planning polygons
and future-ЖК points carry no map-able geometry on the frontend yet — left
as backend follow-ups, not faked.

Add Конкуренты / Будущие проекты / Зоны риска Leaflet layers to the Site Finder
analysis map (MiniMap→SiteMap) with per-layer toggles in CpLayerControlPanel
(Конкуренты on by default; pipeline + risk off). Competitors/pipeline render as
distinct CircleMarkers from analyze lat/lon (#1074); risk zones as GeoJSON
polygons parsed from geom_wkt via a small inline WKT parser (no new deps).
Graceful on missing coords / empty arrays / thin responses. Coordinate order
verified (GeoJSON lon-lat for <GeoJSON>, Leaflet lat-lon for CircleMarker).
3 of 4 layers; future-ЖК (newbuilding) pending newbuilding_listings API exposure
(#1108 built the table). Part of #999.
