CLI "showdefaults" fix

[breadoven]

Fixes use of CLI "showdefaults" Diff/Dump command option so that actual default values are shown rather than the set value. "default" has also been added to the default setting line to make it clear that's what it is.

High-Level Assessment

The PR’s approach is the correct minimal fix: showdefaults should print from the default-value pointer (settingGetValuePointer) rather than the current/copy pointer. The added #default prefix improves readability without changing command semantics. Alternatives like adding a new dump mode or restructuring pointer naming would add complexity without benefit for this bug.
