Implement dynamic handling based on MythicMobs version

[albardoo02]

Description

Due to API changes between different versions of MythicMobs, implement a system to detect the server's MythicMobs version at runtime and switch the internal processing dynamically to ensure compatibility.

To-Do

• Implement a utility logic to detect the current MythicMobs version upon plugin enablement.
• Design an abstraction layer/interface (e.g., MythicMobsHandler) to encapsulate version-specific API calls.
• Implement concrete handler classes for each targeted MythicMobs major/minor version.
• Implement a provider/dependency injection flow to instantiate the correct handler depending on the detected version.
