Responses API - add default api version for openai responses api calls + Openrouter - fix claude-sonnet-4 on openrouter + Azure - Handle `openai/v1/responses`
- Added `forward_client_headers_to_llm_api` setting in the Bedrock documentation to facilitate client-side header forwarding.
- Updated `completion` function to use merged headers instead of original `extra_headers`.
- Improved request handling in `BedrockConverseLLM` and `AmazonInvokeConfig` to ensure proper header management for `anthropic-beta` parameters.
- Refactored request transformation logic to return the transformed request for better clarity and functionality.
- Renamed `AmazonAnthropicClaude3Config` and `AmazonAnthropicClaude3MessagesConfig` to `AmazonAnthropicClaudeConfig` and `AmazonAnthropicClaudeMessagesConfig` respectively for consistency.
- Implemented `get_anthropic_beta_from_headers` function to extract and handle `anthropic-beta` headers across various transformations.
- Updated request transformations in `AmazonConverseConfig` and `AmazonInvokeConfig` to include `anthropic_beta` parameters based on user headers.
- Added tests to ensure proper handling of `anthropic_beta` headers in different scenarios.
