Local API Access

[muhlba91]

According to https://github.com/hella-info/onyx_api/tree/master?tab=readme-ov-file#local-access, ONYX.Center supports local API access.

The challenge is to disable certificate validation (first priority) and allow certificate pinning (second priority).
Certificate pinning will enhance security and protect against man-in-the-middle attacks. It is questionable if this is required in a local access scenario; however, if we can support it, users are free to use it.

This library needs to be changed to allow passing in the API endpoint and potentially a certificate for pinning.

Supported cases:

• HTTP client passed in: can we overwrite the settings for our sessions to disable certificate validation and/or even perform certificate pinning?
• HTTP client creation: we need to disable certificate validation and potentially allow certificate pinning.
