insights' after_migrate hook connects to the Site DB data source via
ibis.mysql; the ibis 12 mysql backend imports MySQLdb, which frappix
does not ship. Fixes b4lerp migrate failing on bosona.
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.
