* fix(volcengine): handle thinking disabled parameter properly
When thinking is set to {"type": "disabled"} in volcengine provider config,
skip adding the parameter to extra_body entirely instead of passing it through.
This prevents "thinking: undefined" from appearing in request logs.
Fixes#13039
* test(volcengine): fix and enhance thinking parameter tests
- Fixed existing test that expected broken behavior
- Added comprehensive test coverage for all thinking parameter scenarios:
* thinking disabled → omitted from extra_body
* thinking enabled → included in extra_body
* thinking None → included in extra_body as None
* custom thinking values → included in extra_body
* no thinking parameter → empty result
All tests passing, verifying the fix for issue #13039
- Added additional routes for key management operations to the access control logic.
- Improved handling of routes that start with "/key/" and end with "/regenerate" to ensure proper access restrictions.
- 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 `AmazonAnthropicClaude3MessagesConfig` to `AmazonAnthropicClaudeMessagesConfig` in the test file to align with recent refactoring.
- Adjusted the instantiation of the configuration class in the test to reflect the new naming convention.
- Updated test cases to use the renamed `AmazonAnthropicClaudeConfig` instead of `AmazonAnthropicClaude3Config` for consistency with recent changes.
- Adjusted imports and assertions in test files to reflect the new configuration class name.
- 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.
- Consolidated access control logic into a new static method `_check_proxy_admin_viewer_access`.
- Improved readability and maintainability by reducing code duplication in route access checks.
- Ensured proper handling of write operations and parameter validation for management routes.
* Remove litellm_params.client_secret from /model/info
Added pop of client_secret (Azure provider secret) from litellm_params in remove_sensitive_info_from_deployment used by /model/info endpoints
* Added test for litellm.proxy.common_utils.openai_endpoint_utils.remove_sensitive_info_from_deployment
