When the uploaded file contains multiple layers, the response includes
all_layers (for frontend layer-select UI) and previous_source_layer
(pre-selection hint from the most-recent completed IngestJob for this
dataset). Pass layer_name in the request body to target a specific
layer; omit it to get the default first-layer metadata.
