fix(ui): stop leading tag-chip icon clipping on the left edge

The larger size=default chip widened Vuetify's negative start-margin on the
leading kind-icon, placing it left of the .v-chip__content box whose
overflow:hidden (the name-truncation guard) then clipped its left edge.
Zero the icon's negative inline-start margin so it sits inside the clip box;
the chip's 12px padding keeps a comfortable left inset.
