UI: Use arrow icon on context paths

The current `ICON_SMALL_TRI_RIGHT_VEC` uses dark hard-coded colors ([`0.2`, `0.2`, `0.2`])
which makes it impossible to theme and hard to see in dark contexts.

Use `ICON_RIGHTARROW` to match the Outliner's breadcrumbs. This icon uses `TH_TEXT` so it's visible as long as the rest of the text is.
