Plugin header tidy-up. No behaviour changes — safe to update. - \`Plugin URI\` now points at the GitLab project (\`gitlab.nolle.engineering/tools/customer-map\`) where source, releases, and changelog live. Previously linked to a non-existent landing page. - \`Author\` is \`nolle.engineering\` (the brand) instead of \`Patric Nolle\` (the individual).
