You configuration contains other layers than your example request and the srs file is missing. So I couldn't reproduce your setup.
What I noticed though is that the srs block in the globals is not indented (mapproxy-util serve-develop warns about that) and supported_srs/supported_formats are options of the source itself and do not belong in the req block.
And now I see that you are making a WMS-C request:
MapProxy directly returns tiles from the cache with tiled=true and it will never do any reprojection, tile-merging or _format_ conversion. Since the cache is in JPEG you cannot make a WMS-C request for PNG.

Try to add `transparent: true` to the req block of the overlay.
