Add Azure OpenAI computer-use-preview Support

[rizardo-maker]

I added Azure OpenAI support for the computer-use flow, including a new azure_openai provider path that uses the Azure OpenAI SDK with the computer-use-preview deployment. The backend now accepts Azure endpoint, API key, deployment, and API version settings, and the Flutter UI was updated so users can select Azure OpenAI from Settings and First Run setup. I also updated the README and .env.example, and added a focused test for the Azure client wiring.
I also cleaned up repo hygiene by ignoring local .venv, .DS_Store, and *.egg-info files so they don’t get committed.

I’m a bunny with Azure keys,
Hopping through clouds and APIs.
Endpoints tucked in, deployments bright,
Securely stored and wired just right.
Tests thump softly—what a delight!

Update the README’s other provider summaries to include Azure OpenAI.

This table now lists Azure as supported, but nearby descriptions still say the project supports only OpenAI and Anthropic. Update those summaries so users do not receive contradictory provider guidance.
