Loïc Wisniewski cc71811d89 Research the Fleet Office, and give it one hull
Fleet Offices sit behind a new Berth Authority doctrine. It costs ore and no
research points, deliberately: points come only from conquering a planet,
conquering needs a fleet, and the fleet caps at its opening hull until an
office exists - so pricing the fleet's own gate in them would lock a player
behind a fight that one vessel has to win first. The research unlocks the
STRUCTURE; capacity is still the built, supplied thing #219 made it.

The tree gains a sixth lane for it, so the branch that fleet size vacated is
occupied again rather than reading as a hole.

Also fixes a shape #216 exposed: a stationed transporter drew a hull written
into its own script while a delivered one drew the definition's, and the
transporter's definition declared none at all - so one in flight was an
empty polygon. Both vessels now draw the definition, and a test pins that
the two paths agree. The repair drone had the same fault, off by two units.
