Add classic Monopoly

[serrebidev]

Summary

• Add Classic Monopoly with buying, auctions, rent, buildings, mortgages, trades, jail, Chance and Community Chest, debt, bankruptcy, and optional Free Parking jackpot rules.
• Fix Monopoly card transaction messages so Chance and Community Chest payouts/fees no longer say "for card".
• Hide the passive Monopoly turn menu for idle non-current players while preserving required auction/debt/trade prompts and the Escape action menu.
• Add in-game Monopoly rules documentation based on the implemented game and Hasbro's official Monopoly Classic instructions.

I did a lot of manual play testing of this first.
