Add FuneralFinder v2 — quick-form stepped search widget

- 4-step vertical form: intent, planning-for, type, location
- Sequential unlock: each step enables when the previous is filled
- Step circles (48px, brand-200) transition to brand-500 check on completion
- Connector lines between circles for visual progression
- Conditional logic: arrange-now auto-sets step 2 to "Someone else"
- CTA disabled until location filled, trust signal below
- Display serif heading + subheading with divider
- Critique 33/40 (Good), Audit 18/20 (Excellent)
