Merchant Dashboard

Allow stores to print shelf-talkers for products such that we can display ratings, product image, and descriptions in a nicely printed label that we can print and put on the shelf in the store

We should be able to edit customer contact details ourselves (phone & email). If a customer obviously enters an incorrect email address (eg. @gmail.con) or a phone number (i.e., including the 1+area code), we should be able to fix this ourselves.
