feat(ui): context filters only clickable when there is relevant data #1017

Situation
At the moment, every sector and region identified in the metadata ends up a selectable in the context filters (detail view and comparison view). This is confusing as most selections will not yield any relevant information.

Solution

• Like on the "Coverage" component, banners for Sectors and Geographies should only be filled if there is underlying data to be displayed. Otherwise they should remain outlines only.
• When there is nothing to be shown, i.e. they are outlines only, then they should not be clickable.
• Availability of benchmark data OR availability of key features or dependencies is sufficient for a sector or region to be considered available
