Implement ban functionality
- Added ban module - Added Ban and Unban commands, supporting banning and unbanning players through various command parameters. - Added timestamp formatting method in Utils utility class for displaying ban expiration times - Introduced PlayerErrorCode enum defining various error codes including ErrBan - Added dual ban checking for both IP and user during player login - Optimized login failure responses to provide specific error reasons and parameters
