Merge #20153: wallet: do not import a descriptor with hardened derivations into a watch-only wallet
538be4219ae7e65862e4aff540af88c9421e6061 wallet: fix importdescriptor silent fail (Ivan Metlushko)
Pull request description:
Currently `importdescriptor` command will successfully import a descriptor with hardened derivations into a watch-only wallet while silently failing to expand the descriptor to fill the cache. This leads to a broken wallet state and failure to load such wallet due to missing cache on subsequent restart.
