Builds the provider on the AI module's OpenAI base class, which is a breaking change: requires drupal/ai 1.4, the three-argument getClient() is gone and textToImage() was rewritten. Adds Responses API support, a separate model name, an option for max_completion_tokens, structured output schema validation and clearer API errors. Run updb.
Small release on the 1.1.x line. It splits the Azure deployment name from the model name and fixes one translation bug. Run update.php after upgrading.
