Add missing shortNames to MCPRemoteProxy, EmbeddingServer, and MCPRegistry CRDs

[ChrisJBurns]

Summary

Three CRDs (MCPRemoteProxy, EmbeddingServer, MCPRegistry) were the only ones lacking shortName in their +kubebuilder:resource markers, while all other 8 CRDs had them. This adds shortNames for consistency, so users can use kubectl get rp, kubectl get emb, and kubectl get mcpreg instead of typing full resource names.

Closes #4592

• Enhancement (non-breaking change which adds functionality)
