EB-2: felt spend - turrets burn a shared Charge pool, ledger-fed Fabricator mints it from Ore

Mined Ore now has an ongoing sink: a ledger-fed Fabricator converts Ore->Charge
(1 Ore -> 3 Charge / 30t) and turrets spend Charge per shot, soft-failing (no
shot, no cooldown burn) when the shared pool runs dry.

- ResourceId.Charge=4 rides the existing [GhostField] StorageEntry ledger (no new wire).
- TurretFireSystem: single ledger resolve + atomic spend / soft-fail / partial-refund.
- Fabricator.InputFromLedger (byte, server-only) feeds input from the shared ledger,
  read live in-loop so two machines split a finite pool; both modes deposit to ledger.
- HudSystem: violet Charge chip + global quiet-turret cue when siege && Charge==0.
- StorageMath.TotalOf backs the affordability read; catalog re-enables the Fabricator (4 entries).

See DR-033.
