test(spring-boot): Move the Boot 4 WebFlux sample's tests into the module

Adds an integrationTestWebflux suite to sentry-spring-boot-4 that
mirrors the Boot 3 one, adjusted for Spring Boot 4: the webclient
starter for WebClient.Builder, the restclient starter that
TestRestTemplate needs, Jackson 3, and @AutoConfigureTestRestTemplate.
The Todo test reads the port with @LocalServerPort because
TestRestTemplate's root URI doesn't hold the port on Boot 4.0.

The Boot 4 WebFlux sample has no system tests left, so it comes off the
system-test runner, the backend workflow and the Spring Boot 4 matrix,
which now runs the new suite.
