New ephemeral, paginated /leaderboard view with Prev/Next buttons. Browsing is private and does not change the pinned board’s stored page.
Placement is now shown only for Master Ball entries; Ultra/Great/Poke entries omit placement to reduce confusion.
Rank tier details are displayed for non‑Master groups when available (e.g., “Ultra Ball Rank 2”); when rank text is missing, the tier is inferred from points.
Admin: /admin_postboard immediately posts all leaderboard pages in‑channel, deletes prior non‑pinned leaderboard posts by the bot, and schedules the next post every N hours (default 12). /admin_stop_postboard stops scheduled posts.
