wallet: handle disabled startup settings

Browse Source 
Return a persistence failure when dynamic settings are disabled so
wallet operations finish with their existing startup-setting warning.
This avoids an uncaught exception in Qt and RPC errors after the wallet
state has already changed. Keep in-memory and no-op updates unchanged.
