fix: localize primary map delivery status

CHANGELOG.md

@@ -18,6 +18,7 @@
 - Added a provenance-gated full-Area query path for official pre-clipped datasets, avoiding redundant intersection of every feature against the same detailed municipal/regional boundary while preserving exact rectangle selection behavior.
 - Reduced a live complete-Kempen population/forest analysis from roughly 92 seconds to 2.8 seconds of API work while retaining the exact official totals.
 - Grouped dated population and forest snapshots into one current source plus an optional historical disclosure, translated remaining user-facing status/download/model-evaluation text and made municipality selection explicitly optional.
+- Replaced the last primary-map `features`/`PostGIS` delivery message with a plain Dutch zoom instruction and user-facing object counts.
 - Added focused scope filtering, command construction, boundary resolution, multi-NIS provenance, full-Area correctness, temporal-language and frontend-label tests; the full readiness gate now passes with 571 tests.
