Verify a report receipt

Checks whether a receipt block was issued by Tamperlens and whether it covers the report you send with it.

Tamperlens never stores the documents it inspects, so it cannot reproduce a report to settle a dispute. The receipt is the alternative: you keep the report and its receipt, and this endpoint confirms the pair.

Send the report exactly as you received it, including the id. Remove the receipt key itself, a receipt cannot cover itself, or leave it in place; both are accepted, and it is stripped before hashing either way.

valid: false carries a reason: bad_signature means we did not issue this receipt at all, while report_mismatch means the receipt is genuine but the report you sent is not the one it was issued for. Those are different problems and the endpoint will not collapse them.
