refactor: extract common integration test logic into abstract base classes (#473)
refactor: extract common integration test logic into abstract base classes - Move duplicated test methods from WebFlux and WebMvc integration test classes to abstract base classes - WebFluxSseIntegrationTests, WebFluxStreamableIntegrationTests now extend AbstractMcpClientServerIntegrationTests - WebFluxStatelessIntegrationTests, WebMvcStatelessIntegrationTests now extend AbstractStatelessIntegrationTests - Each concrete test class now only implements transport-specific setup methods (prepareClients, prepareAsyncServerBuilder, prepareSyncServerBuilder) - Eliminates ~1300+ lines of duplicated test code across multiple files - Improves maintainability by centralizing test logic in reusable base classes - Updates WebMvcSseServerTransportProvider to use builder pattern - Adds new HttpServletSseIntegrationTests extending AbstractMcpClientServerIntegrationTests - Removes HttpServletSseServerTransportProviderIntegrationTests - Standardizes timeout configurations and client setup across all integration tests Signed-off-by: Christian Tzolov <christian.tzolov@broadcom.com>
