Connect Spice Banker sealed battle spending and saved settlement

Prototype one through three own spice as a separate sealed battle commitment. Reserve funds alongside actual force support, add strength only for the surviving skilled leader, and settle once through existing versioned writes. Apply the documented card/core-rule interpretation: payment survives leader death or loss, except for the sole successful traitor caller. Keep printed disc strength and bounty unchanged. Normal income awaits its deferred-custody ruling; combined modules remain gated.

Validation: 54 focused tests; typecheck, lint, 4490 offline tests, production build and 43 HTTP tests passed. Independent rules, privacy, persistence and UI review completed. SQLite tests cover reserved-spice diversion, concurrent settlement, traitor waiver and legacy plans. Browser exercised a three-spice commitment, pending refresh, actual +3 strength and payment, and restored private cards and the next decision. Two genuine four-profile Basic/Advanced samples completed without rejected candidates but did not use Banker spending.

Following another reported outage, the server remained healthy. Preserved all 461 opening rooms and original seat/recovery rows (495 rooms after QA/HTTP). SQLite integrity and foreign keys passed. A fresh online backup captured all 495 rooms, and browser refresh restored the QA seat. No restart or reset was needed.
