Stop execution when the audit save reports lost ownership. Both paths claim running but continue to the provider after SaveExecutionIfStatus reports a status conflict. If the reaper has failed the row, a provider purchase can start after that failure. Treat ErrExecutionNotInExpectedStatus as a lost claim; retain best-effort handling for other audit-write errors.

Review comment at @internal/purchase/approvals.go at line 416:
Treat ErrExecutionNotInExpectedStatus from SaveExecutionIfStatus as a lost claim
and return before executeAndFinalize; keep best-effort handling for other
audit-write errors. Apply this in internal/purchase/approvals.go at line 416 and
internal/purchase/scheduled_fire.go at line 94, classifying the status conflict
as a lost fire in the scheduled path.

// Attribution is best-effort once the atomic flip has landed --
// dropping these audit fields must not stop the purchase from firing.
