This commit updates the logic for handling binding exceptions in the
management context when it is separate from the application context.
The changes allow the exception details to be visible to
DefaultErrorAttributes without causing the servlet container to
detect an error condition.

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.
