a60d9eb9e6b6a272a3fca8981d89a55955dced55 Bugfix: Wallet: Lock cs_wallet for SignMessage (Luke Dashjr)
Pull request description:
cs_desc_main is typically locked within scope of a cs_wallet lock, but:
CWallet::IsLocked locks cs_wallet
...called from DescriptorScriptPubKeyMan::GetKeys
...called from DescriptorScriptPubKeyMan::GetSigningProvider which locks cs_desc_main first, but has no access to cs_wallet ...called from DescriptorScriptPubKeyMan::SignMessage ...called from CWallet::SignMessage which can access and lock cs_wallet
Resolve the out of order locks by grabbing cs_wallet in CWallet::SignMessage first
-------------
Note this is currently only an issue for the GUI (which lacks sufficient testing apparently), but can be reproduced by #26082 (CI fails as a result)
