Refactor websocket logging and error handling

- Introduced new logging functions for websocket requests, handshakes, errors, and responses in `logging_helpers.go`. - Updated `CodexWebsocketsExecutor` to utilize the new logging functions for improved clarity and consistency in websocket operations. - Modified the handling of websocket upgrade rejections to log relevant metadata. - Changed the request body key to a timeline body key in `openai_responses_websocket.go` to better reflect its purpose. - Enhanced tests to verify the correct logging of websocket events and responses, including disconnect events and error handling scenarios.
