fix(beszel): GPU-LXC temperature alerts watch the GPU, not the hypervisor CPU

Browse Source 
nh3-ml1's first Temperature alert (2026-09-25 2105, 88.8 C) was nh3-pve's CPU
package during the nightly vzdump; the GPU sat at 47 C. hwmon is not namespaced,
so an LXC's agent reports its host's coretemp sensors under the LXC's name.

- hosts/{nh3,esh}-ml1.yaml: SENSORS=-coretemp_*,acpitz (blacklist); GPU and
  NVMe temperatures verified still reported.
- Hub: Temperature >95 C / 5 m on nh3-pve and esh-pve for the CPUs (i9-13900H
  TjMax 100 C; nh3-pve 2-hour averages reach 88 C on busy days).
- nh3-pve README: runs warmer than esh-pve; workload confounds it, check
  airflow on the next visit.
