Add new environment variable named AI_API_TOKEN

[kevinbackhouse]

I've also kept the old name, COPILOT_TOKEN, for backwards compatibility.
I've replaced AI_API_ENDPOINT with a function. Otherwise, capi.py reads the value from os.environ as soon as capi.py is imported, which is usually before load_dotenv is called, so storing the value in a .env file didn't work.
Replacing AI_API_ENDPOINT` with a function also enabled me to make the unit test simpler.

Pull request overview

This PR introduces a new environment variable AI_API_TOKEN to replace COPILOT_TOKEN while maintaining backwards compatibility, and converts AI_API_ENDPOINT from a module-level constant to a function to ensure proper initialization order with load_dotenv().

Key Changes:

• Added get_AI_token() function that checks for AI_API_TOKEN first, then falls back to COPILOT_TOKEN
• Converted AI_API_ENDPOINT constant to get_AI_endpoint() function to avoid premature environment variable reading
• Simplified unit tests by eliminating the need for module reloading
