Describe the Bug

Specifying a useAsTitle on a field that doesn't exist triggers an undecipherable error: TypeError: right-hand side of 'in' should be an object, got undefined when visiting the List page of the Collection.

Reproduction Steps

1. Add the following Collection:

   
   import type { CollectionConfig } from "payload";

export const Example: CollectionConfig = { slug: "example", admin: { useAsTitle: "email", // this field does not exist }, fields: [], };

export default Example;

Fixed in https://github.com/payloadcms/payload/pull/8122

We'll throw a clear error if the useAsTitle is invalid
