refactor(transport): Replace SseEmitter with queue-based SSE implementation in WebMvc transport

Replaces Spring's SseEmitter with a custom BlockingQueue-based SSE implementation in
WebMvcSseServerTransport for improved event delivery control and connection management.

The new implementation:
- Uses BlockingQueue for reliable event queuing and delivery
- Adds proper session management with dedicated SSEEvent record
- Improves error handling and timeout management
- Adds comprehensive integration tests

Resolves #57
