MAF-19914: docs: update example plan paths in dispatch skills

Earlier rounds intentionally left these two example paths on the old
docs/superpowers/plans/ convention as out-of-scope. The exclusion was
the wrong call: example paths should follow the same naming pattern
the rest of the codebase advertises, otherwise readers infer that the
old convention is still valid.

Update both example paths to docs/plans/YYYY-MM-DD-<name>.md so every
plan path in the repository points at the same convention.
