HTTP 400 errors with some netbox API operations

I've noticed in the last release or so that during initialization:

We are seeing some error 400s coming out. I'm not sure why but we need to debug it. For the most part from what I can tell autopopulation is working, so I'm not holding up the v25.11.0 release for it, but it needs to be resolved.

The issues probably stem from one or more of these issues with the Device-Type-Library-Import library:

• Update netbox_api.py - Fix Error creating manufacturers (Only some of the manufacturers were imported.) netbox-community/Device-Type-Library-Import#173
• Error creating manufacturers 4.3.0 netbox-community/Device-Type-Library-Import#172
• Error creating manufacturers on Netbox 4.2.7 netbox-community/Device-Type-Library-Import#169
• Error creating manufacturers - netbox v3.7.1 netbox-community/Device-Type-Library-Import#123

Temporarily going to point to my fork with some of the PRs from the main branch pulled into try to resolve this issue.
