refactor: title generation logic

- Changed the title generation endpoint from POST to GET, allowing for more efficient retrieval of titles based on conversation ID.
- Implemented exponential backoff for title fetching retries, improving responsiveness and reducing server load.
- Introduced a queuing mechanism for title generation, ensuring titles are generated only after job completion.
- Updated relevant components and hooks to utilize the new title generation logic, enhancing user experience and application performance.
