fix(matching): Match SAB to Sonarr by downloadId first

Sonarr tracks the exact SAB download ID (nzo_id). Now tries to match
by downloadId first, then falls back to title matching. Also adds
debug to show if matches are via downloadId vs title, and logs
downloadIds in history to verify the link exists.
