Michal 7f551081ad labsim: capture BGP, dual WAN and both ISP VMs as code ...

The sim's routing config existed only as running state on the VMs. It was
applied by hand over SSH, so rebuilding a VM lost the rehearsal and nothing
recorded why any of it was shaped the way it was. The two ISP VMs were not
referenced anywhere in the repo at all.

sim-net-config.py generates all four roles; sim-net-apply.sh applies them over
the serial console, or diffs them against the running VMs. Verified reproducing
live state exactly before committing: primary 40/40 commands, secondary 16/16,
isp-dhcp 19/19, isp-pppoe 21/21.

Carries the reasoning that was previously nowhere: RFC 8212 needing policy in
both directions or the session carries zero prefixes; probe targets that must
not double as system name-servers; default-route-distance 210 rather than
no-default-route, which blanks new_routers and hands the default route to the
backup line; and the WI-8 bootstrap bug that pinned /32s fix.

Dropped a stale `pppoe-server interface eth0` on isp-pppoe (a NIC that does not
exist there) so a green drift check stays meaningful.
