Set safety_identifier to openai-guardrails-python

[steven10a]

Fixing safety_identifier implementation

• Previously we were incorrectly adding safety_identifier as a HTTP header
• Changed to use the supported safety_identifier parameter

Note safety_identifier is only supported by the normal OpenAI responses and chat.completions endpoint. Not implemented for Azure or third parties.

Pull Request Overview

This PR replaces the header-based safety identifier approach with a parameter-based approach for tracking guardrails library usage with the OpenAI API. The change removes the _openai_utils module that injected headers and instead conditionally adds a safety_identifier parameter to API calls when using the official OpenAI API (excluding Azure and alternative providers).

Key changes:

• Removed _openai_utils.py module containing header-based safety identifier logic
• Added _supports_safety_identifier() helper function in three locations to detect compatible clients
• Updated all OpenAI client instantiations to remove prepare_openai_kwargs() wrapper calls
• Added conditional safety_identifier parameter to LLM API calls based on client compatibility

This comment is misleading. The test creates a real Azure client and tests it with isinstance(), which is correct for llm_base.py. However, the chat.py and responses.py implementations use class name string matching instead, not isinstance checks.

Suggested change

	# Azure detection happens via isinstance check, but we can test with class name
	# In llm_base.py, Azure detection happens via isinstance check (this test is correct).
	# Note: chat.py and responses.py use class name string matching instead.

[nitpick] The __all__ list was reordered alphabetically, but this appears to be an incidental change unrelated to the PR's main purpose of refactoring the safety identifier. The previous ordering grouped related items together ('LLMConfig', 'LLMOutput', 'LLMErrorOutput', then functions). Consider reverting this change to keep the PR focused on its core objective.
