The Python cockpit-bridge frees spawn-pipe fds only at GC time; the Van
Router page's ~12 cockpit.spawn calls every 5s saw-toothed the bridge to
its 1024-fd soft limit, so the polkit admin-escalation spawn failed with
"Too many files open" whenever it landed near a peak.
Two-sided fix:
- vanrouter.js gathers all read-only status in ONE `sh -c` spawn per
refresh, sections delimited by @@vr:<name>@@ marker lines (~12x less
pipe churn). Mutating actions unchanged.
- cockpit-session@.service drop-in raises LimitNOFILE to 65535
(hard limit is 524288), installed by deploy.sh.

Join station MACs against dnsmasq leases (IP + hostname), with the
kernel's br0 neighbor table as a fallback IP source for static-IP
clients.

vanrouter.js hardcoded the 5GHz iface; generalize to an APS list
(iface + hostapd unit + band label). The Access Points card now renders
a status line, client table, and Restart button per band, and the WAN
table excludes both AP ifaces.

New "Battery / Power" card shows mains vs battery, charge % with a severity-
colored bar (only bites while on battery), the last alert level, and the
configured warn/shutdown thresholds. van-battery now includes warn_levels +
shutdown_level in /run/van-battery/state.json so the card stays self-describing
instead of hardcoding the numbers.

Single sysfs sample loop drives three jobs off one daemon (modeled on
van-failover):
- live state at /run/van-thermal/state.json; new Cockpit "Temperatures"
card reads it in the existing 5s loop (no per-refresh `sensors` shell-out)
- journal alerts on ok<->warn<->crit crossings, with clear_margin hysteresis
- throttled, self-rotating CSV history at /var/log/van-thermal.csv
Sensors resolved by hwmon name+label (coretemp/Package id 0, nvme/Composite),
never by hwmonN index (not stable across boots). Defaults: CPU warn 80 /
crit 95, NVMe warn 65 / crit 70. deploy.sh installs + enables the service.
