==== Goal
This task is for displaying the information we fetch for the Compare tab in {T238714}.
==== Acceptance criteria
Mock: https://prtksxna.github.io/wmf-cu-goodplace/compare.html
The information is placed in one table like the one in the Epic ticket:
{F31607508, width=800}
===== Things to note:
* There is a new tab next to //Preliminary check// for //Compare// (need to come up with a better name though).
* In the initial load, rows are grouped together by username, followed by IP address (for different UAs). If an IP and associated username were both looked up, club the row with the username.
* Include option to sort in the //Username//, //IP address// and //User-agent// column headers. We'll make the sorting actually work in a separate task.
* There is a visual indicator to distinguish the usernames and IPs explicitly entered by the user. They are bold with a darker background.
* There is a button for the //(10 from [3 other users](https://en.wikipedia.org))// information that would allow the user to click it and add the new rows to the table. We'll add the functionality to actually append the new rows in a follow-up ticket. !
* The username links to the user-page for the user.
* The IP address does not link anywhere. Make them black.
