feat: Introduce SessionEventBroadcaster and SessionCompletionHandler for improved session management

- Added SessionEventBroadcaster to handle broadcasting of session lifecycle events, consolidating SSE broadcasting and processing status updates.
- Refactored SessionRoutes to utilize SessionEventBroadcaster for broadcasting events related to new prompts, session starts, and completions.
- Created SessionCompletionHandler to centralize session completion logic, reducing duplication across multiple endpoints.
- Updated WorkerService to initialize SessionEventBroadcaster and pass it to SessionRoutes.
