fix(map): read all relevant selection sources

-The primary workflow is deliberately short: choose a municipality or the complete region, choose a data theme, drag a rectangle on the MapLibre map and read the resulting PostGIS evidence. Releasing the drag runs the active theme query and every other available theme query for the same EPSG:4326 bbox. The active `area_id` constrains every drawn/manual selection to `bbox ∩ Area`; `Volledig werkgebied` uses a bbox enclosing the Area and therefore resolves to the exact persisted geometry. The result panel shows selection area, exact intersection totals, active-theme density, source identity and bounded feature properties. Map rendering remains capped at 1,000 features while `total_feature_count` reports the exact database count.
+The primary workflow is deliberately short: choose a municipality or the

-In the Flanders workbench, ruimtebeslag, open ruimte, population density,
-node value and service level may appear as `Op aanvraag`. Drawing a rectangle
-or choosing a municipality uses the existing backend Job/Dataset flow to
-acquire and persist those five official rasters for the exact selection, then
-shows all available semantic metrics together. Identical requests reuse the
-persisted artifact. The complete Flanders Area is deliberately unavailable for
-these rasters because it exceeds the backend safety ceiling; this does not
-limit vector or partitioned bathymetry analysis of the complete region.
+In Flanders, a bounded selection can combine current NGI administration and
+Statbel population with GRB buildings/roads/water/parcels, the governed
+thematic rasters, DHMV terrain, VMM flood hazard, BWK/Natura 2000, DOV soil and
+VHA historical profile points. Every acquisition still uses the existing
+backend Job/Dataset flow and identical requests reuse the persisted artifact.
+The complete Flanders Area is deliberately unavailable for monolithic
+on-demand rasters because it exceeds the backend safety ceiling; this does not
+limit ordinary rectangle analysis or audited regional partitions.
 
 Detection Lab only lists ready imagery rasters. Governed height, flood-hazard
 and thematic policy rasters remain available in the map explorer but are
