FinP2P Ledger Proof Verifier

Verifies a FinP2P Ledger Proof in Hashlist mode against a caller-supplied secp256k1 public key. Recomputes the FinP2P Hashlist digest (fixed field order, group hash then hash-of-group-hashes, per finp2p-docs.ownera.io) and reports whether it matches the receipt's stated hash, and separately whether the secp256k1 signature over that digest verifies against the supplied key. Zero network calls; the verification key is caller-supplied, never resolved by this tool. Two independently reported results, never fused into one boolean. Makes no claim about ledger finality, settlement, or acceptance. EIP-712 typed-data proofs are out of scope (Hashlist mode only).
