Refuel a ship where it is (fill or an amount, at the local price),
switch its refuel policy, and order emergency fuel when the sim offers
it (fuel at 2.5x the local price, cost added to the loan). The save
fields and migration landed in Step 15.4.

Ships carry fuel: a leg burns from the tank at departure (no credits),
dispatch needs the fuel on board (not-enough-fuel), a leg's fuel cost
is fuel burned x the tank's average price, and Auto top-up refills on
landing with what the credits cover. The save gains tank fields (save
version 2, migration fills every tank). Market ships arrive full; the
deal's ships come with a quarter tank to keep the balance targets.
