Reverse a scan
Undoes an accepted scan (e.g. an accidental duplicate scan) by recording a linked reversal scan — the original is kept for audit and the pass counts as not redeemed again. Returns both records; 404 when the scan does not exist or was already reversed.
Requires the scans:write scope on the access token.
