feat: operationalize Flemish land and nature themes

+## On-demand forest, agriculture, nature and soil
+
+In the Flanders workspace, `Bos`, `Landbouw`, `Natuurwaarde` and `Bodem` are
+discoverable before local provisioning. They remain `Op aanvraag` until the
+user selects a municipality or draws a bounded rectangle. Forest and
+agriculture use thematic raster analysis; nature value and soil use the
+persisted-vector GeoJSON pattern. The browser calls only the GeoIntel API and
+never contacts WCS, WFS or OGC providers directly.
