complete onboarding UX v2

Tasks C, H, I from the plan:

- Forgiving API key validation: add Printify UUID format and Printful
  length validation, validate on blur for fast feedback, helpful error
  messages with specific guidance

- External links UX: verified all external links use <.external_link>
  component with target="_blank", rel="noopener noreferrer", icon, and
  screen reader text

- Input styling WCAG compliance: increase input border contrast from
  ~3.3:1 to ~4.5-5:1 across all theme moods (neutral, warm, cool, dark)
