Enum dropdown not showing if they are in a different schema

### Version Information

Server Version:
CLI Version (for CLI related issue): v2.12.0

### Environment

docker/self-hosted

### What is the current behaviour?

'locale' table is setup as enum in Schema named 'enum':

Definition of 'locale':

In another Schema 'public', it shows it as text for all tables:

This is the case for all enums.

### What is the expected behaviour?


It should be a drop down instead of a text field.

The issue is because they are not in the same schema.

In above screenshot, it worked correctly because I put the enum in the same schema.

### How to reproduce the issue?

1. define an enum in a new schema
2. foreign key it from a table in another schema

Reproduce the issue in the table editor by defining an enum in one schema and referencing it from a table in another, then compare it with an enum in the same schema. Trace how the editor identifies enum columns across schemas; done means the cross-schema enum is rendered as a dropdown rather than a text field.
