🥗🧹🥔✨ Marketplace: Show DeliveryArea in `Order::EmailReceiptCompon…

…ent`

- #1325
- #1324
- #1326

I didn't use the `marketplace_order, :full` factory outside of the
`Order::PlacedMailerPreview` and `Order::ReceivedMailerPreview`; and
apparently had flubbed the implementation; so that was not working...

So I fixed it and used it in the `Order::EmailReceiptComponent` spec to
test the `Order#delivery_area`

I also noticed we didn't wire in associations between the
`Marketplace::DeliveryArea` into the `Marketplace::Cart` and
`Marketplace::Order` so I added some specs for those.
