Add JSON storage support for clans, homes, and protected blocks

- Implemented the **Clan** class to load, reload, and save clan data (including chunk locations and ownership) using Gson and the Paper API.
 - Added the **Homes** class to manage player home locations, converting JSON-stored coordinates into Bukkit `Location` objects.
 - Created **ProtectedBlocks** and **ProtectedBlock** classes to handle protected block data (owner, key, and block location) from JSON.
