feat(all): add hunting and events, commerce and rewards, binary calendars, GameData caching and login diagnostics

Implement hunting AP and progress, event tasks, exchanges, games, stories and actions; connect battle and reward handling.

Add CashShop plugin and installation, server purchases and entitlements, recharge rules and plugin version metadata.

Distribute binary calendars independently; cache GameData in memory and fix single-connection query deadlocks.

Improve automatic login and recovery diagnostics; document configuration and release flows.
