Product edition: UI tweaks needed

[g123k]

Hi everyone,

Here is a list of simple things to fix in the product edition:

Photo picker

• The edit (last button) is not aligned on the left
• The language picker doesn't use the full space for the InkWell

Bulk editor

• The title in the AppBar is inconsistent in terms of size with other screens

** Card**

I'm not sure that the use of a divider with no entry is relevant

** Sub screens**
The height of the Cancel button is taller than the other
