StaticInvoice::is_offer_expired to check the offer's expiry#4594Conversation
The std-only `StaticInvoice::is_offer_expired` accessor delegated to `InvoiceContents::is_expired`, which compares `created_at + relative_expiry` against the current time — that is the *invoice*'s expiry, not the offer's. The `_no_std` sibling and `flow.rs:: enqueue_static_invoice` already treat the two as distinct checks. A payer or forwarder using the std API to decide whether to honor a static invoice would therefore get the wrong answer in either direction: forwarding offers the issuer has already retired (when the invoice is still fresh), or refusing offers that are still valid (when the invoice has aged past its `relative_expiry` but the offer itself has no `absolute_expiry`). Route the std accessor through `InvoiceContents::is_offer_expired` so both the std and no-std paths consult the offer's expiry. Co-Authored-By: HAL 9000
