Fix ClientSideAim RPC spam from observer clients

Use GetLocalRole()==ROLE_AutonomousProxy instead of GetRemoteRole()==ROLE_Authority
to restrict the ClientAim/ShootRepCSA RPC path to the owning client only.
Observers (SimulatedProxy) early-out instead of attempting to send Server RPCs
on weapons they don't own, which was spamming "No owning connection" warnings
and doing useless work. Default ClientAimUpdateFrequency raised to 60 Hz.
