Make the agent info ribbon scroll with the rest of the content

[gdiazlo]

Describe the solution you'd like

A user navitages to the agent overview page using a device with an uncommon resolution ( like a MS Surface) and it renders like this:

That render hasn´t been scrolled, but look like if it were scrolled to the bottom of the page.

We want to redesign the page so the ribbon with the agent status and information scrolls like the rest of the content.

Analyzing the code, it is found that the component that shows the agent details is public/components/common/welcome/agents-info.js

this component is used in public/components/common/welcome/agents-welcome.js

where the design problem is found
