AUDIT-WP-0005-T04.

Disposition: there are no pre-production records. No audit-core SQLite store
on this host, no mock-file-backend output, and no audit-core pod, deployment
or PVC on railiance01 - the only audit-* PVC there is OpenBao's own audit
device. Consistent with the history: WP-0003-T03 was cancelled before the
receiver was ever deployed, so every SQLite store that has existed was a test
fixture. Nothing is being discarded because nothing was ever accepted outside
tests.

The tool is built anyway because the SQLite path stays reachable - the
entrypoint falls back to it when AUDIT_CORE_DATABASE_URL is unset. If that
fallback is ever used in anger the records are audit records, and writing the
migration afterwards under pressure is the wrong time.

audit_core.migrate_store and `python -m audit_core migrate-store` transfer
events, dead letters and secret-finding counters. Records keep their original
event_id, payload_hash and accepted_at, which is why this bypasses accept():
that stamps acceptance with the current time, and a migration that rewrote
acceptance times would destroy the evidence it exists to preserve.

Idempotent, and verification reads back from the destination rather than
trusting the write path. A destination record with a differing payload hash is
reported as a conflict and left untouched - silently overwriting a stored audit
record is the same class of failure as losing it. Conflicts and failed
verification exit non-zero; a partial migration is not a success.

Tests 71 -> 77.
