Staff structure workspace and simulated battle lab

What changed

Alliance Controlcenter Structures shows slots 11–15, current occupants and construction progress, plus a staff generator for the selected alliance.

Staff can queue a three-tick build or immediately activate a timed structure. Occupied slots, invalid coordinates and duplicate active types are rejected.

Satelite Uplink includes a random simulated battle lab. Reports also appear in Journal and load the original fleets into the battle calculator.

Simulation changes no real fleets, resources, asteroids or Multihunter movement evidence.
