Run online, offine chat actor, director tests for any supported provider

- Previously online chat actors, director tests only worked with openai.
  This change allows running them for any supported onlnie provider
  including Google, Anthropic and Openai.

- Enable online/offline chat actor, director in two ways:
  1. Explicitly setting KHOJ_TEST_CHAT_PROVIDER environment variable to
     google, anthropic, openai, offline
  2. Implicitly by the first API key found from openai, google or anthropic.

- Default offline chat provider to use Llama 3.1 3B for faster, lower
  compute test runs
