Merge quattro and route refreshes through omarchy-update-pacman

Upstream now runs every Omarchy-owned pacman transaction through the
hidden omarchy-update-pacman helper so a mid-transaction systemd reexec
cannot kill it. Keep the deferred pre-refresh-pacman hook and the
command-scoped sudo wrapper, and call the helper from the refresh and
channel commands; the wrapper still applies to the helper's own sudo.

The sudo boundary fixture copies the helper into its root and runs a
systemd-run stand-in that execs the wrapped pacman step in place.
