Deduplicate missing/scraped stats; show matched from latest run

- total_scraped: unique songs ever seen playing (not per-run sum)
- total_missing: unique songs ever reported not in Plex library
- total_matched: matched_count from most recent successful run
- Added (144) stays cumulative — each add is a real playlist event
