refactor: streamline message handling in Conversations component

- Reorganized imports for better clarity and consistency.
- Removed unnecessary parameter from `handleSendMessageWeb` function to simplify its signature.
- Updated error handling in `sendMessage` thunk to enhance readability by consolidating the dispatch call for error responses.
