[Feature] Castle Siege Implementation

[golansoffer]

Castle Siege, a core event in MU Online that players love for its intense guild battles and strategic gameplay. Including this event would greatly enhance our community’s engagement and bring authenticity to the classic MU experience.

Suggested Features:

1. Guild vs. Guild warfare mechanics.
2. Scheduling system for regular siege times.
3. Rewards that reflect the original MU Online setup (e.g., exclusive access or buffs).

I had much fun on castle sieges on GMO, so this is definitely on my to-do list 👍

To make this work, we first have to implement guild alliances, which is a bit more complicated feature which will touch a bit of code in every part of the project (DataModel, Persistence, GuildServer, GameLogic, GameServer, Packets) 😅
