1. Temp password for auto-registered users:
- Store password in _woonoow_temp_password user meta (CheckoutController)
- Add {user_temp_password} and {login_url} variables (EmailRenderer)
- Update new_customer email template to show credentials
2. WC page redirects to SPA routes:
- Added redirect_wc_pages_to_spa() in TemplateOverride
- Maps: /shop → /store/#/, /cart → /store/#/cart, etc.
- /checkout → /store/#/checkout, /my-account → /store/#/account
- Single products → /store/#/products/{slug}
3. Removed shortcode system:
- Commented out Shortcodes::init() in Bootstrap
- WC pages now redirect to SPA instead
