feat(automations): auto-email invoice on wire-transfer placed and on fulfillment

- New ShopSettings fields: autoEmailOnWireTransferPlaced,
  autoEmailOnFulfilledNonWireTransfer, wireTransferGatewayNames.
- New Automations section in settings with two toggles + gateway list.
- orders/create webhook now fires automation 1 (wire-transfer placed).
- New orders/fulfilled webhook fires automation 2 (non-wire-transfer fulfilled).
- Shared helper services/invoice/automations.server.ts handles classification
  and idempotent generate+send (skips if already sent).
- Webhook subscription for orders/fulfilled added to all 3 app tomls.

This is the non-Plus fallback for Shopify Flow, whose custom-app actions
are gated to Plus stores only.
