Add organisation link to finder

In order to display the organisation Metadata, we must tag each Finder in Panopticon with it's Organisation and fetch this on load.

This PR displays a link back to the Finder's tagged Org. It also styles it to look like the metadata in the rest of GOV.UK and adds a CSS reset to fix some browser stylesheet margins going on. I also fixed a spacing issue this introduced on the Filter Results button.
