refactor: improve web search plugin and middleware integration

- Cleaned up the web search plugin code by commenting out unused sections for clarity.
- Enhanced middleware handling for the OpenAI provider by wrapping the logic in a block for better readability.
- Removed redundant imports from various files to streamline the codebase.
- Added `enableWebSearch` parameter to the fetchChatCompletion function for improved functionality.
