When the node rejects the wallet's RPC login (bad rpcuser/rpcpassword), the
status bar showed developer jargon ("Auth failed — check rpcuser/rpcpassword")
and the only action was Reconnect, which just repeats the failure. Now a
dedicated AuthFailed banner reason surfaces "Wallet can't sign in to the node"
with a plain-language detail and a real fix: Restart node for the embedded
daemon (regenerates its cookie creds) or Open config folder for an external one
(to fix DRAGONX.conf). Driven by a new rpc_auth_failed_ flag (set on the auth
path, cleared on each connect attempt), with evaluator unit tests.
