Replace the old ticket picker (dorm/shared/single × full/weekly) with a
simpler model: €300/week base registration with opt-in toggles for
accommodation and food, which are invoiced separately after acceptance.
- Merge form steps 11+12 into single "Weeks & Options" step (13→12 total)
- Add "Select all 4 weeks" toggle, accommodation yes/no + preference, food toggle
- Live price summary (€300 × weeks)
- Simplify Mollie pricing to flat per-week rate
- Add need_accommodation and want_food DB columns with auto-migration
- Update confirmation/admin emails and Google Sheets sync
