UI Builder should allow me to specify fields that come from relationships in my components

### Describe the feature you'd like to request

I'd like to be able to build components that use data from related models.

### Describe the solution you'd like

For example, if I have a `Post` hasOne `Author`, I should be able to design a component representing a Post where the `post.author.name` can be used as a field.

### Describe alternatives you've considered

Right now, my only option is use to separate `Post` and `Author` properties, and write my own logic to make sure I pass in the ones that are related to each other.

Additionally, if I use two separate data models in my Post view component, I cannot use the `Collections` feature to make list views for my Posts.

### Additional context

_No response_

Start by tracing the UI Builder component-field workflow and the Collections feature described in the issue. Define how a Post hasOne Author relationship exposes post.author.name in a component and still supports Post collection list views; confirm the behavior for related-model fields before considering the work complete.
