Add condition tests for MCP client transport auto-configurations

- Add SseHttpClientTransportAutoConfigurationTests to verify conditional bean creation for HTTP client transports
- Add SseWebFluxTransportAutoConfigurationTests to verify conditional bean creation for WebFlux client transports
- Test both auto-configurations with various conditions including presence/absence of WebFluxSseClientTransport and MCP client enabled/disabled states
