Compact detection source tile rows

 - Detection Lab keeps the complete persisted detection collection available to the existing MapLibre overlay and QA/QC flows.
 - The results table renders 50 rows by default and provides 25/50/100 row sizes plus previous/next controls. This bounds DOM work for dense AOIs without discarding or resampling detections.
 - Selecting another run, changing a class/confidence filter or loading a new result collection resets the visible table to page one.
+- Source tiles display their filename for compact scanning while retaining the complete persisted path in a hover tooltip.
 - Pagination is intentionally client-side over the canonical persisted response; detection API contracts and GeoJSON output are unchanged.
