Make Fremen allied revival grants cancelable

Bind the original Fremen/ally/turn grant before Karama allowance or prevention.
A prevented grant leaves intrinsic free rates and prior payments intact. Permit
late grants under the explicit provisional Recruits current-rate policy, with
shared controls, minimal bot support and native public chronology evidence.
Complete rules and browser/deployed acceptance remain open.
