Previously, AutoConfigureMockMvc used Spring Security's default filter
ordering, ignoring the value configured by SecurityProperties that is
used at runtime. This resulted in different ordering at runtime and in
tests.

This commit updates the configuration for AutoConfigureMockMvc to
import the Spring Security filter auto-configuration, thereby ensuring
that the ordering configured via SecurityProperties is applied.

Previously, when lazy initialization was enabled, STOMP-based WebSocket
messaging would not work as the stompWebSocketHandlerMapping bean was
not initialized and CONNECT requests would go unanswered.

This commit adds a LazyInitializationExcludeFilter that causes the
stompWebSocketHandlerMapping bean to always be initialized eagerly.
This triggers initialization of the WebSocket transport allowing
requests to be received and processed.
