 note: Fix missing default values in unredacted print-config command by introducing confmap.WithUnredacted MarshalOption.

   Resolves an issue where the unredacted mode output omitted all default-valued options. By introducing a new MarshalOption to disable redaction directly at the confmap encoding level, the unredacted mode now preserves all component defaults natively without requiring post-processing.
