CAMEL-23904: Fix CamelBeanDumpTest NPE caused by uninitialized picocli fields

[gnodet]

Summary

Claude Code on behalf of Guillaume Nodet

Fixes https://issues.apache.org/jira/browse/CAMEL-23904

CamelBeanDumpTest.testRequestsBeanDumpAndRendersBeans always fails with a NullPointerException (ERROR, not assertion FAILURE) because the test constructs CamelBeanDump directly without picocli command-line parsing.

Root cause: Picocli's @CommandLine.Option(defaultValue = "...") only takes effect during command-line parsing — it does NOT set the Java field's initial value. When the command is constructed directly (as in tests), String fields remain null. The scope field being null causes a NPE in matchesScope()'s switch statement, since Java's switch on a null String throws NPE.

Fix:

• Add Java field initializers (= "name", = "all") to String fields in CamelBeanDump matching their picocli defaultValue, so the command works correctly when constructed outside of picocli parsing
• Set the missing scope and nulls fields in the test to match the picocli defaults

Test plan

• CamelBeanDumpTest passes (both test methods)
• Module builds successfully (mvn -DskipTests install)
