integration: HA cable-pull lifecycle test

Add DisconnectFromNetwork/ReconnectToNetwork on TailscaleClient
backed by pool.Client.DisconnectNetwork.

Exercise single-router fail+recover either side, sequential dual
failure, and simultaneous dual failure. The dual-failure legs
assert no flap to a known-bad primary; the single-router-return
legs check traffic only because docker network disconnect
transiently fails probes on sibling routers.

Fails on parent; passes after the fix.
