Function reconcileApprovalsForSummary

Recovery primitive: given a run's suspended RunSummary, heals every CURRENTLY suspended step whose exact (suspendedAt, resumeCount) fingerprint has no approval record of ANY status, then files it fresh. Safe to call on every status() read of a suspended run, rather than only after a confirmed bridge failure, because per step:

• any record (any status) already bound to the CURRENT fingerprint means nothing to do — a matching pending/claimed/escalated record makes queueApprovalForSuspension's own idempotent create() a no-op anyway (this skips the round-trip), and a matching DECIDED record means the decision landed but its resume has not (yet, or ever, on the wedge path this exists for) re-queued the next gate — re-filing would double-file a gate correctly waiting on its own resume, the decide -> resume in-flight window;
• otherwise, every STALE OPEN record for that step (pending/claimed/ escalated, bound to a suspension the step has since moved past — produced e.g. by the raw grant-free resume route re-suspending the step while an earlier request still sits open) is SUPERSEDED first (ApprovalService.supersedeStale: a CAS transition straight to 'rejected', system-attributed, audited as approval.supersede, never through decide() — so it never touches the run) before the fresh file, closing the loop where a stale-but-open record otherwise never heals (every poll re-lists, finds the same open record via the open-step uniqueness index, and re-files nothing). A stale DECIDED record needs no supersede — it is already terminal and excluded from grant derivation by its own (non-'approved', or fingerprint-mismatched) status.
• if a supersede loses its CAS (a real decision won the race between the list() above and the supersede), this step is left alone for this round entirely — no fresh file — rather than clobbering or double-filing over a decision that just landed; the next status() read re-evaluates against a fresh summary and a fresh list().

Delegates the actual filing to queueApprovalForSuspension against a copy of summary narrowed to only the healed paths, so a step with a live or in-flight record is never touched. requestedBy defaults to the SYSTEM principal because generic workflow reconciliation cannot reliably recover the initiating principal. Agent hosts persist the original requester and pass that id explicitly so separation of duties survives eviction and filing retries.
