#116: the Spacial Workshop, and the drones that mend what waves break

Modelled on the transport hub, deliberately and closely: drones belong to a
workshop rather than to the player, are provisioned when it is built, are
never a production order, and are upgraded at a ship lab like any other
vessel. Anything that already knows how hub transporters behave knows how
these do, and Drone Bays raises the count at workshops already standing -
the same shape as Freight Yards and Garrison Bays.

What a repair COSTS is the one new idea. It is a share of the building's own
price, in proportion to how much of its health is gone: levelling a crafter
and rebuilding it costs its full price, and patching one up after a wave
costs a fraction, the fraction being the damage. The ore is spent when a
drone LEAVES, so two drones cannot be sent to the same wall and spend twice
for one load of repair, and a building demolished in transit sends its load
home rather than swallowing it.

"Required resources are sent to the spacial workshop": the workshop asks hub
logistics for the ore its outstanding repairs will need, exactly as a gas
burner asks for gas, because building_logistics_deficit now takes the larger
of the definition's static buffer and what the world actually demands. There
is a ceiling on that, so one badly-mauled base cannot pull the whole bank
into a single workshop and starve everything else.

Worst first: the structure closest to coming down is the one a repair is
worth most on.
