The firewall page now manages zones (assign each LAN or tunnel, add and
remove zones) and rules with zone, address and port on both sides plus the
protocol. router.firewall.zones declares zones without members and rules
take sourcePorts. The temperature chart draws every thermal zone and hwmon
sensor; the overview defaults to 15 minutes, 1h stays an option.

LANs can sit on an 802.1Q VLAN (`vlan` on a trunk `interface`); networkd
creates the device and brings the trunk up. LANs belong to a named `zone`
(default: their own name). Traffic inside a zone is forwarded freely, traffic
between zones is denied unless a `router.firewall.rules` entry allows it
(protocol, ports, optional destination inside the target zone).
Internet access is now opt-in per LAN (`internet`, default false), replacing
the previous allow-out default. Assertions reject unknown zones, bad
destinations, duplicate devices, over-long device names and a WAN trunk.
Kea subnet IDs now come from the network address so adding LANs does not
renumber them and orphan persistent leases.
Tests: a five-VM `vlans` check (untagged + two VLANs, shared zone, one-way
rules, per-host destination restriction), new assertion cases, parseNet unit
tests, and shared test tooling in tests/common.nix.
