feat: integrate AuraPay payment provider

Full integration following PayPear/RollyPay patterns:
- API client with X-ApiKey + X-ShopId auth, HMAC-SHA256 webhook verification
  (sorted keys, concatenated values, secret key #2)
- AuraPayPaymentMixin with create, webhook, finalize (all side effects), status check
- CRUD, model, migration (0060), PaymentMethod.AURAPAY enum
- Webhook endpoint, cabinet topup, bot handler with sub-options (card, sbp)
- Admin panel: AURAPAY category in bot_configuration + system_settings_service
- Config: AURAPAY_ENABLED, AURAPAY_API_KEY, AURAPAY_SHOP_ID, AURAPAY_SECRET_KEY
