[Housekeeping]: Add support for NetBox v4.3

[pheus]

Proposed Changes

Update the NetBox ACL plugin for compatibility with NetBox v4.3. This includes:

• Updating version metadata to reflect support for NetBox 4.3
• Adjusting to any breaking changes in the NetBox API, particularly the GraphQL schema
• Running compatibility tests to verify full functionality on NetBox 4.3

Justification

NetBox v4.3 introduces breaking changes, especially in its GraphQL API. Updating the plugin ensures it remains functional and users can safely upgrade their NetBox instances without losing access to the ACL plugin. This is part of regular maintenance to keep the plugin aligned with current NetBox releases.

I'd be happy to contribute this and submit a PR to add NetBox v4.3 support.

This work depends on the following open issues, as they address required GraphQL support needed for compatibility with NetBox v4.3:

• [Feature]: Add ACL Interface Assignment to GraphQL #251
• [Feature]: Allow Query for Related Rules of an AccessList in GraphQL #252

It could also benefit from the ongoing test coverage improvements:

• [Housekeeping]: Develop Plugin Tests - Models #47
• [Housekeeping]: Develop Plugin Tests - API #131

While the test-related issues are not strictly required, they would help validate compatibility more thoroughly.
