kdmukai 6268589db0 Reject psbts that falsely claim this seed's ownership 
Every derivation entry naming the signing seed's fingerprint is now
verified during parse() by re-deriving the key from the seed itself.
A claim that does not hold up aborts the parse before any transaction
detail is shown: a false claim on an output is classified as an attack
(fake change) and routed to a dire warning, while a false claim on an
input is reported as inconsistent data with a plain warning. A psbt
whose inputs this seed cannot sign at all is turned away to seed
selection.

The per-scope verification results are recorded in
verified_input_derivation_paths / verified_output_derivation_paths,
the ownership record later stages consume.
