In theory, it should be only one custom account with a given name. However,
users could have created custom accounts with various key scopes. In that case,
'LookupAccount' has a non deterministic behaviour. To fix that, we browse
through all key scopes (deterministically) and return the first account we found.
By default, P2TR addresses are used for changes. However, some users
might encounter some problems with this change. We add the possibility
to define a custom address type in FundPsbt for default/imported accounts
(only P2TR for now). If no address type is specified for these accounts,
we will use P2WKH by default.
Fixes#6626.
If either of the two fields FinalScriptSig or FinalScriptWitness is set
on an input of a PSBT then that results in most of the fields of that
input not to be serialized in the packet anymore, since the input is
considered to be complete.
But because a signer isn't supposed to set any of the Final* fields,
this was wrong from the beginning. Only the finalizer will set those
fields.
