rpc: Push down safe mode checks

This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.

This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.
