feat: Enhance Stream Management with Abort Functionality

- Updated the abort endpoint to support aborting ongoing generation streams using either streamId or conversationId.
- Introduced a new mutation hook `useAbortStreamMutation` for client-side integration.
- Added `useStreamStatus` query to monitor stream status and facilitate resuming conversations.
- Enhanced `useChatHelpers` to incorporate abort functionality when stopping generation.
- Improved `useResumableSSE` to handle stream errors and token refresh seamlessly.
- Updated `useResumeOnLoad` to check for active streams and resume conversations appropriately.
