A client joining a dedicated server with Celestria will crash

[wchen1990]

When both client and server has Celestria the client will crash on Neoforge. This can also be replicated in the dev environment.

Exception:
java.lang.ClassCastException: class net.minecraft.client.player.LocalPlayer cannot be cast to class net.minecraft.server.level.ServerPlayer

The relevant line of code is here:

Celestria/common/src/main/java/eu/midnightdust/celestria/Celestria.java

Line 68 in a42ffc8

world.getPlayers().forEach(player -> PacketUtils.sendPlayPayloadS2C((ServerPlayerEntity) player, new WelcomePayload()));

Just needs a simple a type check or a check to see if the world is server side.

This also occurs on 1.21.1 NeoForge on a single player world as well.
