The Groovy DSL was missing support for the nullChannel, which is a special channel that discards messages (acts like /dev/null). This prevents users from using nullChannel in their Groovy integration flows. Add unit tests to verify: - nullChannel can be used at the end of a flow - nullChannel can be used after transform operations - Messages are properly discarded without exceptions

The original implementation had left the beans as dead code after initial tests were deemed to weak. However, the dynamic flow increased the amount of code to maintain. Changes include: - Replace dynamic flow creation with `@Bean` configuration methods - Add shared `nullCheckWireTapChannel` bean for message verification - Simplify test methods by using autowired channels - Add `@since 7.0.1` annotation to `nullChannel()` method documentation
