Replace More button by a step by step assistance

Instead of the "More" button in the paragraph below each screen title, a "See steps / How to proceed" button should be more obvious and explain step by step:

• how to do a simple configuration
• explain vocabulary and fields
• see if i need a template / an automation chain / a resource first
• see where to check the result in the app.

+ remove descriptions + add help links to the confluence doc

E.g. Concepts should be explained: layouts, widgets, are generic words but mean something precisely for us. Maybe a visualisation of what is a layout, a widget, or links to small animations can help. (this part can be moved in another task if needed.)
