Describe the bug
A relationship field set to read-only (via column restriction on the view) causes an error: "User does not have permission." When viewing with a custom role, a 403 error in the network tab occurs when a user with that role accesses the screen.

To Reproduce
Steps to reproduce the behavior:

1. Import the attached app
2. Preview the app as a manager
3. See the error being thrown

Expected behavior
If Role X has read access to View/Table Y, which includes a relationship column (at least readable) linking to Table Z, then X must be able to fetch Z's schema.

No error should be thrown whenever viewing the forms attached to the view. The form field is read-only, but a value should be shown if you use a read/edit form block.

Screenshots
View as a manager

The form that causes the error: You can see the relationship is blank on an update type.

As discussed privately, this is either a bug with the relationship picker field hitting an API endpoint it shouldn't, or a backend issue where tables related to each other should be able to fetch each other's schema regardless of access.

I'm rewriting the entire relationship picker field because it's awful, so I'll soon see where the core problem lies.

Discussed on Linear - this is actually due to the related tables permission level and is not something that can easily be fixed (a larger piece of work is required).
