give Claude turns a brand-orange message card (T-144)

Extends the card treatment to Claude's text responses: _userCard becomes
a shared _messageCard(label, accent, body) used by both turns. The user
stripe stays the theme focus colour; Claude's stripe + label use Claude's
brand coral-orange (#D97757) — a fixed brand accent, not a theme token —
so the two speakers are accent-coded at a glance.
