Kristoffer Dalby 7b080e8cfa servertest, integration: regression tests for HA both-offline recovery ...

Cover the user-reported sequence in #3203: two subnet routers
advertise the same prefix, both go offline, one returns. Three
variants:

  - servertest TestRoutes/ha_secondary_recovers_after_all_offline:
    in-process Disconnect/Reconnect.
  - integration TestHASubnetRouterFailoverBothOffline: tailscale
    down/up between two routers, asserts both server and client
    state restore.
  - integration TestHASubnetRouterFailoverBothOfflineCablePull:
    iptables -j DROP between router and headscale, mimicking a
    real cable pull that breaks the ESTABLISHED long-poll.

All three pass on main — the production failure narrows to a
direct State.Connect/State.Disconnect race that the cable-pull
harness does not reliably hit, addressed in a follow-up commit.
The tests stay as regression coverage for the user's scenario.
