refactor(resource-usage): inline pill switcher + icon-only daemon actions

Replaces the heavyweight Radix Tabs strip with a compact segmented pill
switcher in the popover header, and moves the Restart daemon and Kill
all sessions buttons to icon-only triggers in the top-right of the same
header. Removes the full-width footer and the unused Tabs primitive
import. Tooltips carry the verbs so the icons stay scannable.
