Refactor role handling in OpenAI request processing for improved clarity and functionality

- Simplified variable initialization in `browser.go` for readability.
- Updated error handling in `request_logger.go` with better resource cleanup using deferred anonymous functions.

Refactor API handlers to use `GetContextWithCancel` for streamlined context creation and response handling

- Replaced redundant `context.WithCancel` and `context.WithValue` logic with the new `GetContextWithCancel` utility in all handlers.
- Centralized API response storage in the given context during cancellation.
- Updated associated cancellation calls for consistency and improved resource management.

- Replaced `apiResponseData` with `AddAPIResponseData` for centralized response recording.
- Simplified cancellation logic by switching to a boolean-based `cliCancel` method.
- Removed unused `apiResponseData` slices across handlers to reduce memory usage.
- Updated `handlers.go` to support unified response data storage per request context.
