Offline-verify a Factory lifecycle station receipt's ed25519 signature (signed_by/signature, added #1475/#1768) against SaSame's trusted issuer key — the same key trust_pubkey and verify_mcp_cert already use. Detects any receipt content altered after signing, or a receipt that was never actually signed by SaSame. Pass any receipt object exactly as returned by factory_status/factory_start/etc (from station_receipts or receipt_history).
