Custom tables names should be used when tracking relationships

### Version Information

Server Version: 2.1.1

### Environment

OSS

### What is the expected behaviour?

Custom table names should be used when tracking (new) relationships.

### What is the current behaviour?

Custom table names are NOT suggested when tracking a new relationship. The original/underlying table name is used instead. This makes the "track all relationships" button completely useless to me.

### How to reproduce the issue?

1. Create tables `a` and `b`, with `b` having a foreign key to `a`
2. use custom names `my_a` and `my_b`
3. track relationships, the original names will be used instead of the custom names (but this can be edited)
4. clicking "track all" won't allow modifying the name

### Screenshots or Screencast

1. table definitions

2. table relationships (expecting my_bs and my_a)

3. schema relationships

Start from the “track all relationships” entry point and the relationship-tracking flow described in the reproduction steps. Reproduce the case with custom names `my_a` and `my_b`, then trace where suggested relationship names are generated from the underlying foreign-key tables. Done means both individual tracking and “track all” use the custom names.
