Feat products edit view

Created by: Eval160

Rename the class "form-login" to "custom-form" and upgrade it to be able to use it everywhere Custom the checkbox/radiobuttons form and add stimulus to toggle active class To do later: custom the ugly upload file input (improve ui/ux, add a file preview, do not delete the old file if it's not loaded again,....) add the option to create new categories (only premium account maybe?)
