state: keep a prefix mapped when no router is available
...
Peers keep the routes of an offline or expired router, as on Tailscale.
The previous primary keeps the prefix, else the lowest-ID approver;
never one the prober declared unreachable.

policy/v2: refuse check SSH rules with tag sources
...
A check asks the source's user to log in again, and a tagged node has
none. Tailscale SaaS refuses the rule; headscale accepted it.

policy/v2: need every dst node for a tests accept, no range sources
...
An accept passes only when each node behind the dst is reached, as on
Tailscale SaaS; a deny keeps its rule. A CIDR, "*" or autogroup:tagged
src names no user or host, so its test fails.
