CAMEL-23226: Fix exit codes for validation errors in camel-jbang commands

[gnodet]

JIRA: CAMEL-23226

Summary

Many camel-jbang commands return exit code 0 (success) when validation fails, which breaks scripting and CI/CD usage where non-zero exit codes are expected on errors.

• Fix return 0 to return 1 in 17 commands where validation errors (missing PID, invalid arguments) incorrectly returned success
• Affected commands: CamelBeanDump, CamelBrowseAction, CamelHistoryAction, CamelLoadAction, CamelRouteDumpAction, CamelRouteStructureAction, CamelSendAction, CamelSourceAction, CamelSourceTop, CamelStartupRecorderAction, CamelStubAction, CamelThreadDump, EvalExpressionCommand, RouteControllerAction, TransformMessageAction, PluginDelete, Jolokia

Test plan

• Verify commands return exit code 1 when required PID is not specified
• Verify commands still return 0 on success
• Verify scripting patterns like camel get beans --pid=invalid || echo "failed" work correctly
