fix(tor): reconnect relays on Tor OFF too, not just ON

Relay reconnect was only triggered when Tor transitioned to Active.
When toggling OFF, relays stayed on the dead SOCKS proxy and never
reconnected over clearnet — feed went blank.

Now triggers reconnect on both Active and Off transitions, so relays
switch between proxy and direct connections when toggling Tor.
