Improve ban cache sync and update dependencies

Enhanced CacheManager to use database time for ban updates, improving multi-server consistency and handling of status changes. Increased PlayerManager's semaphore limit and improved player/bans refresh logic to ensure status changes are detected even when the server is empty. Updated author and version metadata, commented out duplicate event registration, and bumped CounterStrikeSharp.API dependency to 1.0.346.
