Add bounded Flanders thematic analysis

 tiles, product identifiers remain server-allowlisted and other raster
 pipelines retain their smaller independent limits.
 
+The Flanders browser workflow uses these same endpoints on demand. It never
+performs a startup import or direct browser WCS request: an explicit
+municipality or drawn rectangle starts five bounded acquisitions, followed by
+the existing persisted-raster analyses. Exact request hashes reuse ready
+Datasets. A full-Flanders raster request remains blocked by the same 60 km and
+30 million cell limits. Dataset metadata labels only Areas named
+`Gemeente ...` as `coverage_scope=municipality`; regional Area clipping is
+stored as `bounded_selection`.
