- F-01: derive the dedupe key from submission content (form id + mapped values)
instead of a per-request token, so identical re-POSTs / retry-after-error
collapse to the existing quote. Keeps the per-request lock; adds a content lock
race guard and a 30-min recent_delivered_by_dedupe short-circuit.
- F-12: refuse resubmit of an already-delivered transaction (AJAX + worker).
- F-18: scope the resubmit self-recovery guard to the content dedupe key so a
customer's different event is no longer skipped.
- F-05: anonymize PII on stale failed/pending rows via the cron; add delete_by_email
and wire WP's Erase Personal Data eraser.
- F-13: exempt stranded delivered rows (no entry_id) from the retention purge.
