[Mobile][FR] Add image workflow improvements for mobile

[halr9000]

Description

Right now it's too many clicks to add an image. And once you add a block you still have to click on the block and then choose one of the options before you can actually get started adding an image.

Suggestions

• One click to open upload dialog immediately
• Different single click to add block and open block dialog to choose from existing options

Impact

Sometimes very often, when I'm adding images.
