[Stats] Stats page modified to filter by Tag. It currently only works by Category

These are the stats which are currently available: https://meta.discourse.org/t/visualised-traffic-statistics/44298

we want to add a ‘tags’ filter to them, and if the user clicks ‘stats’ in the floating footer it will take them to the stats page opening on that tag.

Scenario 1:

  • user is on ‘webdev’ tag page.
  • user clicks ‘stats’ in the floating footer
  • user is taken to the stats page shown above.
  • the stats page opens showing the stats for the ‘webdev’ tag.

Scenario 2:

  • user is on ‘webdev’ and ‘ruby-on-rails’ tag intersection.
  • user clicks ‘stats’ in the floating footer
  • user is taken to the stats page shown above.
  • the stats page opens showing the stats for the ‘webdev’ and ‘ruby-on-rails’ tag intersection.
