Wire the stats page to filter_url()/stats_links:
- Per-row session links on game superlatives, games-by-playtime, platform
and month rows (game rows keep their detail GameLink, add a session icon).
- Count links: sessions, games, total/refunded/dropped/unfinished/backlog
purchases.
- Cap preview lists to 5 with a 'View all (N)' link passing ?sort= for order
parity; remove the redundant 'All Purchases' list.
- stats_data: carry platform_id for platform links; drop the all-time
games-by-playtime [:10] slice so the view-all count is honest (rendering
caps the preview).
Also make the filter bar's _extract_labeled tolerate bare choice/multi values
so a programmatically-built filter URL renders instead of crashing.
