Introduce MailService as a convenience layer between handlers/services and MailRepo. Provides Send, SendSystem, SendGuildInvite, and BroadcastToGuild methods that encapsulate the boolean flag combinations. GuildService now depends on MailService instead of MailRepo directly, simplifying its mail-sending calls from verbose SendMail(..., false, true) to clean SendSystem(recipientID, subject, body). Guild mail broadcast logic moved from handleMsgMhfSendMail into MailService.BroadcastToGuild.
