Reorder components to move token/filter inside left pane

Created by: mrnugget

This is another step towards https://github.com/sourcegraph/sourcegraph/issues/34201.

This PR

• reorders the components so that the token and the filter row are inside the left pane
• it also fixes the appearance of the loading spinner, so it now has a stable position next to token
• fixes some word-wrapping inside the results

This also shows the loading spinner and the filter and that they're sticky
