fix(cli): allow --changelog flag without specifying version

Fixes bounty issue #1385

When running 'cortex upgrade --changelog' without specifying a version,
the command would exit early if the user was already on the latest version,
before displaying the changelog. This fix moves the early exit check to
after the changelog display, so the changelog is always shown when
requested regardless of whether an upgrade is available.
