fix(fusion_clock): planning port defers when planning ORM not loaded during -u

fusion_clock doesn't depend on planning, so planning's models load AFTER it
during -u and the port saw no data. Now detect planning tables via SQL,
defer (no marker) when the ORM isn't loaded, and finish the port from the
deploy odoo-shell step (full registry). Marker now owned by the method.
