fix: finish end user language sweep

CHANGELOG.md

@@ -15,6 +15,7 @@
 - Defaulted Detection Lab to the configured local YOLO asset, active local model profile and measured operating threshold; model quality remains explicitly review-required rather than presented as production-perfect.
 - Simplified Quality, Downloads, Status and Beheer around end-user tasks without changing API contracts, migrations, persistence or inference behavior.
 - Followed the live browser audit by moving the legacy Mol-only workspace under advanced management, adding friendly regional-boundary dataset names, translating the active model profiles and replacing the empty `waiting` quality status with end-user language.
+- Completed the visible-language sweep for the details control, export preview and provider layer names.

 - Tower rebuilt the AI-enabled all-in-one image successfully; container health, PostGIS 3.6, required schema objects, Alembic head `202607140001`, frontend, API proxy and icon checks passed.
 - The map opened directly on the complete regional workspace with 29 work Areas, no region selector, the full region selected and 466,078 buildings, 88,332 water objects, 84,504 roads and 415,288 parcels available.
 - The browser audit found four remaining presentation leaks: the legacy Mol-only project was still prominent, boundary datasets showed filenames, profile names were English and an empty quality status said `waiting`. These were corrected and protected by the now `561`-test suite.
+- A final visible-language sweep translated the export preview, details control and provider layer chips; the complete readiness gate remained green with `561 passed`.
 
 Next:
 - Extend official population and modern land-use time series from Mol to all 28 municipalities, then expose a guided raster-import and configured-detection run over a drawn map selection.
