Renders a customer testimonial card.

The card body contains (top to bottom):

1. Star row — rendered only when rating (1–5) is provided; fills amber stars then empty stars.
2. Decorative quote mark — a large " in text-muted-foreground/20 for visual interest.
3. Quote text — italic paragraph in normal foreground colour.
4. Author row — avatar (if author_src provided) + name + role/company.

When variant={:minimal}, the card chrome is omitted and the body is rendered inside a plain <div>. For all other variants, the body is wrapped in a PhiaUi.Components.Card.
