nox calls the seats that own each job, not the unassigned controller

The controller nox forwarded every line to is unassigned (issue 1126), so nox
answered nothing but enrol open. Each line now calls the seat verb or module
tool that owns its job through this machine's console (mesh_call); a line no
seat owns says so and names what to use, never failing silently.
