fix: danger Button uses text-bg, not white (v0.4.1)

White on the danger fill lands ~3.3:1 against tuned dark-theme danger
tokens (e.g. delta's rust at 58% lightness) — below AA for 14px labels.
text-bg follows the primary variant's own pattern (bg-brand text-bg)
and holds ≥4.5:1 on both the kit default and delta's tokens.
