Temporary overlay until the PR reaches nixpkgs-unstable. Fixes
CVE-2026-109618 and CVE-2026-109619. Becomes a no-op and warns at eval
time once the locked nixpkgs ships these versions; delete it then.
Package git.b4l.co.th/newedge/default_thai_company as a frappix app
(pkgs/frappix/default-thai-company.nix) and expose it through a new
frappixAppsOverlay that extends the pkgs.frappix scope. Install it on
the poyerp.newedge.house site on deneb.
