Episode highlights per series: tag by lane, group on Episodes page, move to Finished Book when series ends; v2.9.1

- Highlights get a Series field (Lane A / Lane B / General); legacy highlights count as Lane A
- Episodes page groups highlights under each series' title
- Ending a series (scheduled or manual) moves only that series' highlights onto its Finished Book page; other lane and General stay
- Archived highlights keep working: detail pages, sitemap, scripture index and search include them
