video wishlist processor: log WHY nothing grabbed (no results vs quality reject)

'no acceptable release' was ambiguous — couldn't tell if slskd returned nothing
or returned hits the quality profile rejected. now each item logs 'No search
results for X' vs 'N result(s) for X, none accepted — <reason>' (reason from the
top hit), and the summary tallies '… · N had no results, M rejected on quality'.
makes the slskd-finds-nothing-for-video situation legible.
