All module slugs get reset on reorder.

[Tom-revere]

Description

When using self-nested module and reordering, the slugs for any nested pages get reset when one of the nested items gets reordered.

Steps to reproduce

1. Setup a self-nested module as per the Twill docs.
2. Enable re-ordering
3. Have a parent page and 2+ nested pages, such as below
   
4. As per the above image, manually change one of the nested slugs to something different to default
5. Change the order of the nested pages

Expected result

The order of these pages should update, but the slugs should stay the same

Actual result

The order is updated, but the slugs reset back to their default, as per here:

Versions

Twill: 3.4.1

Laravel: 11.29.0

PHP: 8.3.4

MySQL: 8.0.30

So take the following page order and slugs:

If we change up the order, all slugs are changed by to default:
