Plan every craftable vessel, and stop restating the point cost

#221: the planning centre listed only fleet-eligible hulls, so the two
vessels that most need replacing were the two it could not plan - #216 made
transporters and repair drones wear out, which is what a standing order is
for. It offers everything a crafter can build now.

That needed the census to see them: it counted the fleet, the hangar,
garrisons and transit, but not vessels standing at a hub or a workshop. An
order for a transporter would never have seen the ones already built, and
the crafters would have gone on making more forever.

#222: the ship lab's detail block restated the selected upgrade's research
point cost, which its own card shows a few pixels higher. Removed, with the
parameter and the call-site lookup that fed it.
