Importer: set asset mime type from file extension

Browse Source 
Uploaded manifest assets previously became application/octet-stream because the
Blob carried no type, so images/audio/pdf didn't display or thumbnail correctly.
Derive the mime from the extension. (Existing deduplicated assets keep their old
mime; only fresh uploads are affected.)
