Add a docker-network-disconnect primitive — `DisconnectFromNetwork` / `ReconnectToNetwork` on `TailscaleClient`, backed by `pool.Client.DisconnectNetwork` — so an integration test can faithfully simulate the cable-pull scenario the issue reporter observed in Proxmox. Iptables-based simulations leave the socket open at the container kernel and miss the bug. Use it in `TestHASubnetRouterFailoverDockerDisconnect` to assert the no-flap invariant: once primary has failed over from r1 to r2 and r2 also loses connectivity, primary must not switch back to the still-offline r1. The assertion fails on the current branch — the all-unhealthy fallback in `electPrimaryRoutes` flips primary to the lowest-NodeID candidate regardless of online state. Locking the failure in via TDD before designing the fix. Updates #3203
