As a server owner, I want a way to edit my configs in a GUI like I would be able to on a client.

Describe the solution you'd like
Allow mods to register their configs as server-modifiable. When the mod in question is present on server and client, a command (added by FL) can be used such as /flconfig <modid>. Server side checks permission, serializes necessary config data and sends to the client, which then spins up a config GUI to edit from. Upon save, client sends the updated config back to the server which loads it in.

Server owners must explicitly opt in to this in a config before anyone has access to this, and even then, they should be able to limit who has access via permission manager, allowlist, or maybe permission level.

Additional context
Challenges:

• Knowing which ConfigBasedSerializables to sync - may have to be provided when registering for this command
• How to get the Config GUI Builder to take in the server's configs instead of the client's - maybe back up client configs then load server configs on the client, then switch back to client configs once they save/cancel?
