feat(ui): thin kind-coloured border on tag chips so they don't wash out

The tonal fill (esp. character = info) is intentionally faint and blends into
the dark tag rail. Add a thin border in each chip's own kind colour via
color-mix on currentColor (the tonal chip's themed foreground), defining the
edge without changing the fill. Theme-aware in both light and dark.
