The Syscoin PSBT fee override must validate the current previous-output metadata when calculating fees. This change checks non-witness transaction identity and output, rejects inconsistent metadata, and recalculates cached fees while preserving allocation burns and unsigned previews. Witness-only metadata still requires a trusted previous-output source from the caller.

Updates bitcoinjs-lib and bip39 to patched versions and adds CI for Node 24 and 26.

Validation: 636 offline unit tests and Standard lint passed. Additional synthetic Pali, Sysnode, Ledger and Trezor compatibility tests passed using mocked devices and RPC; no public transactions or physical hardware were used.
