The modem management subnet is stream-specific (it shares stream's `wan`
interface), so it no longer belongs in the shared routing-common. Drop the
`modem` network assignment and configure the address directly on stream's
`wan` (modemV4). The firewall reject and DNS wan-A-record skipBroadcasts that
existed only because of the modem move to per-box options
`my.homeRouter.{firewall.untrustedRejectV4,dns.wanSkipBroadcasts}`, set solely
by stream. river needs neither: its ONT sits on a separate interface already
blocked by the interface-based forward rules.

Clients were handed both routers' real addresses as resolvers, so a downed
router meant per-query resolver timeouts. Serve pdns-recursor on the VRRP
VIPs (with non-local bind so the backup can pre-bind them) and advertise the
VIP via kea and radvd, so DNS follows the master. untrusted advertises
Cloudflare over v6 to match its v4 config.
ipsec started before the WAN's public IP was up: stream's wan carries a
static modem address that satisfies wait-online before the DHCP lease, so
libreswan loaded its mesh conns (left=<public IP>) unoriented and never
initiated. Gate stream's wan-online.target on the DHCP default route
instead, and mkForce ipsec onto wan-online.target only (dropping the
strongswan/libreswan multi-user.target pull-in) so the gate actually holds
on both boxes.

river's WAN moves to a PPPoE session (Digiweb, over VLAN 10 with baby-jumbo
1508 MTU) driven by pppd, with its ip-up/ip-down hooks toggling a new
wan-online.target. stream keeps its DHCP WAN, so the existing 50-wan /
50-wan-ifb networkd config moves out of routing-common into stream, and the
shared consumers (ipsec, ipv6-clear-default-route) now attach to
wan-online.target instead of depending on systemd-networkd-wait-online@wan
directly.
