fix(thermal): decouple widget click from sort state; add tab-aware routing via PopoutService

- CpuTemperature/GpuTemperature: remove DgopService.setSortBy() from click
- GpuTemperature bugfix: was calling setSortBy('cpu') not 'gpu'
- DankBarContent: replace 20-line manual popout positioning with
  PopoutService.toggleProcessListModal(tabIndex)
- ProcessListModal: add tabIndex to show()/toggle(), clampTab() validator
- PopoutService: showProcessListModal/toggleProcessListModal with tab routing

Fixes: none (no upstream issue; found during fork audit)
