Two gaps in the baseline-reconciliation feature:
- The dashboard claimed to summarise acknowledged drift, but renderIntegrity()
never rendered it. Add a `recon` chip to the integrity summary and a
Reconciliation state-card (accepted/ok/stale counts plus stale items).
- A read-only GET /api/integrity could write the store: list() flushed a
TTL-lapsed ok->stale transition to disk, violating the read-only dashboard
invariant. Add list(persist=False) and use it from the web summary path so
staleness is evaluated in memory without touching the file.
Covered by a new test asserting integrity_report() never rewrites the store.
