FIX [GUI] Home: render LabelsBar chips inside the Labels card

LabelsBar's root sets `flex: 1 1 0` which assumes a horizontal flex
parent. Inside Home's column-flex card the LabelsBar collapsed to
zero height so the operator/operation chips were invisible. Wrap
LabelsBar in a dedicated row container with an explicit min-height
so the chips render.
