4637735aa2 Pin trusted PATH in privileged DNS helper (#8172 )

* Pin PATH to trusted dirs when omarchy-dns holds root

A dev link prepends a user-writable checkout bin/ to sudo's secure_path,
so the passwordless `omarchy-dns Cloudflare` sudoers rule lets root
resolve a bare helper (dirname, install, tee, nmcli, ...) out of that
checkout — turning checkout-write access into arbitrary root execution.
Pin PATH to trusted system directories once EUID is 0, leaving the
unprivileged wrapper phase free to locate sudo/pkexec on the caller's
PATH.

* Assert the trusted-PATH pin is gated on root, not merely present

The EUID assertion matched `(( EUID == 0 ))` anywhere in the file, and require_root has carried that exact test since long before the pin existed. Deleting the pin left the assertion passing, so it stood for nothing: a run with the pin neutered reached the behavioural probe with both greps green. Anchor on the unindented guard and require the pin to be the line it opens, which no other construct in the script satisfies.

* Skip the DNS trusted-PATH probe where user namespaces are unavailable

`fail` ends the file, so a sandbox or hardened kernel that refuses unprivileged user namespaces did not just lose the probe — it took the two elevation assertions below it down as well, reporting a product defect where there was only a missing capability. The non-graphical suites are meant to run on any machine and treat a skip as a passing test, the way require_compositor and plugin-add-test.sh already do. Gate the probe on the namespace it needs and say so when it is absent; the static checks above and the elevation checks below run either way.
