Introduce a compile-time error when a stub entity contributes additional fields to a subgraph

[MohamedSabthar]

Description: A stub entity should exclusively contain key fields; in other words, a stub entity that lacks a resolved reference should not include any fields in its type except for the key fields.

For instance, the following is a valid definition of a stub entity:

@subgraph:Entity {
    key: "id"
}
public type Product record {
    readonly string id;
};

However, the following is not valid:

@subgraph:Entity {
    key: "id"
}
public type Product record {
    readonly string id;
    string name; // 'name' is not a key
};

Hi @MohamedSabthar, I noticed that the issue isn't marked as high priority. If it's not an urgent requirement, could you please assign it to me? I'm still familiarizing myself with open source contributions and would love to take this on. In case I encounter any difficulties, I’ll be sure to let you know so we can reassign if needed.
