1. Remove wishlist setting from customer settings (now in module toggle)
- Removed from CustomerSettingsProvider.php
- Removed from Customers.tsx
2. Remove auto-login from REST API (causes cookie issues)
- Auto-login in REST context doesn't properly set browser cookies
- Removed wp_set_current_user/wp_set_auth_cookie calls
3. Fix cart not clearing after order
- Added WC()->cart->empty_cart() after successful order
- Server-side cart was not being cleared, causing re-population
- Frontend clears local store but Cart page syncs with server
