Fix Python model for Local API (id = None)

[iMicknl]

Fixes #1183

[Copilot]

Pull request overview

Fixes incorrect Setup.id initialization when the Local API omits the id field, preventing attrs internal _CountingAttr objects from leaking into model instances and JSON-like output.

Changes:

• Update Setup.id typing and Setup.__init__ default to correctly support None when id is missing.
• Add/extend tests to assert setup.id is None for local setup fixtures and validate obfuscated repr when id is present.
• Update local connection docs to include the typical :8443 port in the hostname example.
