Point GitHub URLs at omacom/omarchy instead of basecamp/omarchy

The repo moved to the omacom org. GitHub redirects the old URLs, but
`omarchy channel set dev` was still cloning from basecamp/omarchy, which
left every dev checkout with a stale origin remote that confuses gh
(pr create fails with "No commits between omacom:quattro and
basecamp:<branch>"). Update the clone URL, the quattro upgrade tarball,
the update-confirm release link, the systemd Documentation link, and
the manual.
