Tests: EB-2 Charge spend + ledger-fed Fabricator (318/318 EditMode)

Browse Source 
- TurretFireSystem: seed a Charge pool for existing tests; add soft-fail-when-dry,
  consume-one-Charge-per-shot, two-turrets-share-a-finite-pool.
- FabricatorProductionSystem: ledger-fed withdraw/deposit, two machines split via the
  live in-loop read, and a catch-up affordability-clamp regression pin.

See DR-033.
