Improvements in the web application (mobile site html, laravel)

In the web application (online store: site on html, admin on laravel) you need to make the following improvements:

- in the app to align texts, indentations, etc. on 3 pages

- in the basket to fix the return back (add the goods button - go to the previous page)

- error in sending an order (only unauthorized users, if authorized, the order goes away normally)

- in the admin to change the drop list when choosing a category (now that would show the goods in this category, we choose it from the list, you need to do that would first choose the brand, and then the category in it)

-
