anvil: add a Collection Log tab for in-game bingo tracking

[AhmedFathy2001]

Update of the Anvil plugin (companion for the Anvil clan-events platform).

Adds an "Anvil" tab inside the in-game Collection Log that surfaces the clan's bingo tracking in-game (previously website-only):

• A schedule view — your active event plus live / upcoming competitions.
• The bingo board rendered as a square grid or a tile-race track (depending on event type), with a per-tile detail page.
• Weekly SOTW / BOTW leaderboards, and read-only previews of events you're not competing in.
