v2.2: Verkaufsfertig-Fundament — Mollie/Payment-Abstraktion, MwSt/Grundpreis (PAngV), Versandzonen, Bestellmails (Listmonk/SMTP/Log), Feature-Flags

- payments.js: einheitliche createPayment/Webhook-Schnittstelle (Mollie Default, Stripe, Demo); Auto-Provider-Wahl; Mollie-REST + /api/payments/webhook (idempotent); Fake-Key => sauberer Demo-Fallback
- mailer.js: sendMail via Listmonk-Tx / SMTP (nodemailer) / Log-Fallback (email_log); gebrandete Bestellbestaetigung bei paid
- DACH: products.mwst + base_amount/base_unit/base_price_per (Grundpreis); Storefront/Warenkorb/Checkout/Erfolg/Admin mit MwSt-Ausweis + Versand-Transparenz; tax_cents/shipping_cents/country an Orders
- shipping_zones-Tabelle + CRUD + shippingFor(); Admin 'Versand'; serverseitige Versandberechnung in /api/checkout + /api/shipping-quote (Laenderwahl live)
- Feature-Flags (feature_*) + feature()-Helper; Admin Module-Toggles; Newsletter-Gating (Popup/Subscribe)
- Admin-API/Manifest/ai-admin.txt um shipping_zones erweitert; MCP list/upsert/delete_shipping; README/.env.example ergaenzt; Version 2.2.0
