wallet: fix FillPSBT errantly showing as complete

Browse source 
Fix cases of calls to `FillPSBT` returning `complete=true` when it's not
the case.

This can happen when some inputs have been signed but the transaction is
subsequently modified, e.g. in the context of PayJoins.

Also fixes a related bug where a finalized hex string is attempted to be
added during `walletprocesspsbt` but a CHECK_NONFATAL causes an abort.

Reported in #30077.
