Stats read request_cache and output_content, which nothing writes, so
TotalItems and TotalSizeBytes were always 0. They now count
source_content plus variant_content, the size through UsageBytes; a
failed query is still logged at warn. Get counts a miss after the work,
passing the bytes fetched from upstream (0 for a cached source; still
counted when the fetched source then fails), so upstream_fetch_count and
upstream_fetch_bytes move. transform_count is incremented after each
successful image processor call. request_cache and output_content stay
in the schema; dropping them is a separate decision.
