Add map QA evidence drilldown

 - After an area extract, `Save area export` persists the selected FeatureCollection as a normal Export Center artifact (`vector_selection_geojson`) so the handoff remains in project export history.
 - `Save as dataset` persists the same selected FeatureCollection as a derived vector dataset, selects it in the workbench and keeps it queryable through backend `vector_features` for later QA/QC or analysis.
 - Once a map selection has been saved as a derived dataset, the Map workspace can run QA/QC against a selected reference dataset without switching workspaces. The action reuses the existing QA comparison endpoint and shows precision, recall, F1 and persisted quality-check status inline.
+- Map selection QA results also show persisted quality-check id, matches, false positives, false negatives, mean IoU and QA warnings. `Open QA/QC evidence` hands operators to the existing QA/QC evidence drilldown for the full parameters/findings record.
 - The Data catalog shows a compact selected/reference/candidate/source summary and scan-friendly badges. Persisted `reference` datasets are shown as Reference, non-reference vector/GeoJSON layers are shown as QA Candidates for workbench scanning, and raster/other uploads remain Source.
 - Dataset cards explain the recommended next action and use compact two-line action buttons for inspect, map, export/QA and metadata refresh. Disabled actions keep a visible reason, such as `Vector/GeoJSON only`.
 - Raster controls show the latest generated tile manifest path from persisted `raster.tile` jobs and can hand that path directly to Detection Lab or Segmentation Lab with the selected raster dataset.
