fix(web): show a sources count in Sync results, render as a list

syncSources never reported how many sources it actually saved, so the
Admin UI's success message always said the meaningless "sources:
synced" regardless of outcome. syncSources now returns the count saved
(-1 if the fetch failed), threaded through SyncResult.SourcesCount.

Also replaces the single run-on results string (which visually mashed
presets/recents/sources together with no separator) with a real <ul>
list, one <li> per resource, matching the presets/recents diff lines.
Built via DOM APIs rather than innerHTML string concatenation, since
preset/recent names ultimately come from user-editable station names
on the speaker.
