feat: system, gpu, disks and network move to the quickshell islandHEADmaster

The quickshell island's performance panel now shows CPU, RAM,
temperatures, the GPU, disks and network, and warns from the status
pill when something runs hot, fills up, or the public IP drifts from
the pinned one. Two dashboards drawing the same numbers would drift
apart, so the four widgets go, with the disks and public IP samplers.
The island keeps writing ~/.cache/udt/pubip.txt in the same format.
The freed space is left empty for the user to rearrange.
