docs: Three-Step Rule + quiXzoom audit improvements

- EXPERIENCE_AUDIT_QA.md updated:
  - quiXzoom onboarding: 8 specific improvements
  - Headline: 'Fota. Skicka. Få betalt.' (three verbs)
  - First card: show payment upfront
  - 100% card: larger number, smaller text
  - Payment card: remove Stripe, add 'Få betalt varje måndag'
  - Flexibility: 'Jobba när du vill'
  - CTA: clearer pre-registration
  - Key numbers: 100% | /bin/bash | Every Monday | 4K
  - Visual flow: 📷 → ✅ → 💰

- THREE_STEP_RULE.md (v1.0, LOCKED):
  - Universal product summary: Input → Processing → Outcome
  - Landvex: Reality → AI Analysis → Decision
  - quiXzoom: Photo → Approval → Payment
  - Applies to landing pages, onboarding, presentations, UX
  - Verification table for both products

Rationale: Common language between products. Three steps = three seconds.
Every product must be summarizable as Input → Processing → Outcome.
This unifies Landvex and quiXzoom under the same conceptual model.
