Changes:
- created second backend subscription/peer
- ran WG Access agent to apply peer to VM100
- no selector expansion yet
- no mapper changes
- no policy switch
- no backend restart
- private client config saved only under VM121 backup dir, not published

Next:
- if PASS, add VM100 selector entry:
   cs2 canary_vpn4
- then observe cs2 -> 0x204 -> vpn4 traffic.
