kdmukai e1cd05dceb Hold every claim of ours on a multisig output to its script ...

A multisig output lists one derivation path entry per cosigner. The
output check verified only the first entry claiming this seed against
the committed script, so a second claim of ours whose key the script has
no use for went unreported when listed behind our real entry or in the
place of another cosigner's entry (which keeps the entry count at n and
passes the surplus count).

Every entry claiming this seed is now held to the script. To feed that,
the ownership scan keeps every entry it proved per input and output, as
the psbt's own DerivationPath objects, instead of the first one's path.
_derive_with_cache_via_derivation_path is added beside the index-taking
primitive for callers holding such an entry; it reads only the entry's
path, since the single-sig rebuild and the multisig fallback derive at
entries carrying a foreign fingerprint on purpose. change_data keeps the
index-list path the views read.
