Part 7 of #12. Depends on the transporter vessel ticket.

From #12: "there's a limit in the number of a available transporters, more hub needs to be created, or a research in the mothership let each hub have more resources".

Scope

Per-hub cap on stationed transporters.
Building more hubs raises total capacity.
A mothership skill-tree node raises per-hub capacity. GameState.SKILL_TREE and max_fleet_size() already do exactly this shape of thing for fleet capacity - follow that rather than inventing a second mechanism.

Acceptance

Building past the cap is refused with a clear reason, not silently ignored.
Researching the upgrade raises capacity immediately for existing hubs.

Done in f198076. Last piece of #12.

A hub stations BASE_HUB_CAPACITY (2) transporters. Total berths are hubs x per-hub capacity, so building another hub and researching Freight Yards both raise it - the choice #12 asks the player to make.

Capacity follows the same shape as max_fleet_size() (sum a bonus over unlocked) rather than inventing a second mechanism, which is what makes research apply to hubs already built rather than only to ones placed afterwards.

A queued-but-unbuilt transporter holds its berth. Without that, a player could order ten against two berths and only find out when they refused to appear.

Ordering past the cap is refused outright, and the two refusals - no hub at all, versus every berth taken - say which. "Nothing happened" is exactly the bug that was reported against the craft button, so it seemed worth not repeating.

mutation	result
cap not enforced	FAIL (queued a transporter past the 2-berth cap)
queued orders do not reserve a berth	FAIL (claimed 0 berths after ordering 2)
capacity flat rather than per hub	FAIL (2 hubs give 2 berths, expected 4)
research applies only to hubs built later	FAIL (research gave 0 berths, expected +1 per existing hub)

Full suite: 47/47.
