Put refresh confirmation on ResetCreditCoordinator.

refreshAfterRedemption is an exported server operation outside the existing service. Add it to ResetCreditCoordinator["Service"], and have both drivers and its test call the service method. The coding guideline says, “A server capability is a method on a service in its domain folder.” The path instruction likewise says that server capabilities belong in the existing domain service.

Review comment at @apps/server/src/provider/resetCreditCoordinator.ts at line 81:
Add refreshAfterRedemption to ResetCreditCoordinator["Service"] and implement it within the existing domain service instead of exporting it as a standalone server operation. Update both drivers and its test to call the service method, preserving the existing refresh behavior.

Do not treat a failed config/read as an unsupported account.

If config/read fails after a successful reset, nativeUsage becomes false. The snapshot then reports unavailable.reason: "unsupported" with a new checkedAt and no usage windows. refreshAfterRedemption accepts it on the first probe, so the retries never run. The RPC then reports success without new limits.

Requiring present usage windows in the predicate would reject accounts that have no native usage. Those accounts produce the same snapshot, and the previous inline check accepted them. They would retry and then fail with "could not confirm."

Separate a failed config read from a route that does not report usage in CodexProvider.ts, so a transient read failure publishes probeFailed and the predicate retries it.

Review comment at @apps/server/src/provider/resetCreditCoordinator.ts at line 92:
Update CodexProvider’s post-reset snapshot handling to distinguish a failed config/read from a successful read whose route reports no native usage; publish `probeFailed` for read failures while preserving the existing unsupported result for accounts without usage. Then update the `probeFailed` exclusion in `refreshAfterRedemption`’s acceptance predicate so failed reads are retried rather than accepted as confirmed limits.
