fix: keep bounded thematic coverage scoped

 - Exposed all four themes through the existing Flanders map selection flow.
   Provider calls remain backend-only and full-Flanders monolithic requests
   remain outside the bounded safety limits.
+- Prevented bounded municipality rasters from being labelled as complete

+  the active selection has a measured result.
 - Kept source semantics explicit: land-use agriculture is not the definitive
   ALZ parcel declaration series, forest is not a legal forest boundary or
   biomass model, and DOV soil is a 1949-1971 historical baseline rather than
