fix: address per-document audit log review feedback

- backfill DocumentMeta.includeAuditLog from the effective team/org
  setting so documents created before the column keep embedding audit
  logs after deploy
- default includeAuditLog in the webhook payload schema so resending
  historical WebhookCall payloads stays backward-compatible
- allow audit-log embedding to be changed after a document is sent
  (drop the server guards and the editor checkbox lock)
- restore the commented change-detection block in updateEnvelope
