Add world-level autoBan config to globally toggle autoban

[ErwinsExpertise]

This pull request adds a configurable setting to enable or disable the automatic banning (auto-ban) feature in the anti-cheat system. The change introduces a new autoBan flag that can be set via configuration files and is propagated through the server, allowing runtime control over whether anti-cheat violations result in automatic bans. When auto-ban is disabled, violation tracking becomes a no-op and no bans are issued automatically.

Anti-Cheat System Enhancements:

• Added an enabled atomic boolean field to the AntiCheat struct and a SetEnabled method to allow enabling or disabling auto-ban at runtime. All violation logging methods now check this flag before proceeding. [1] [2] [3] [4]

Configuration and Propagation:

• Introduced the autoBan configuration option in both config_dev.toml and config_world.toml, with a default value set to true in the code. [1] [2] [3] [4]
• Extended the World struct and related serializable data to include the AutoBan flag, and ensured this flag is set from configuration during world server initialization. [1] [2]

Channel/World Communication:

• Modified the channel registration handshake so that the world server sends the AutoBan flag to the channel server, and the channel server applies it to its anti-cheat system. The channel server now logs the status of the auto-ban feature at registration. [1] [2] [3]
