Stats UI: per-anime progress rows, status chips, on-hold, streak, detail line

- server: /api/stats top_anime rows enriched — poster, total eps, cur_ep,
  last_seen, status (finished/ongoing/hold heuristic), pace (ep/day),
  sub/dub watch-time split, rewatches (backward jump >60s); new on_hold
  + best_streak top-level keys; optional ?slug= filter (json_extract)
- frontend: 'Most watched' rows = poster + meta + status chip + completion
  bar (ongoing -> hold -> finished order); stat cards swap in on-hold and
  best streak, errors demoted to a one-liner; anime detail page gets a
  progress line (E12/24 · 4h 30m · 2.1 ep/day · status); history cards
  dim + label 'on hold' after 7 days; savePos now includes total eps
- css: .chip, .stat-anime rows, .card.hold, .detail-prog; drop dead .stat-row
- test: test_stats asserts the new fields + slug filter
