Normalize organisms, PaymentStep feedback, cross-page spacing fix

- Organism normalize pass: fix FuneralFinderV3 transition timing
  (200ms → 150ms ease-in-out), add autodocs tag to V3 stories
- Navigation: fix logo a11y — div with role="link" → proper <a> tag
- ToggleButtonGroup: add align (start/center) and direction (row/column)
  props, bump description text from text.secondary to text.primary
- PaymentStep: divider under subheading, lock icon alignment, centre-
  aligned payment options, vertical payment method stack, checkbox align
- SummaryStep: save button → text variant (matches other pages), centred
- All wizard pages: heading mb: 1 → mb: 2 for better breathing room
- Style Dictionary: auto-generate tokens.d.ts, fix TS unused imports
- tokens.d.ts: generated type declarations for 398 token exports
