misc/coverage: Add a focus query parameter to emphasize origin types
When that parameter is used, the lists of origin types it contains will be emphasized in the archive coverage view by adding a red border around the associated bootstrap cards.
Cards content will also be expanded by default and no maximum height will be applied.
The purpose is to emphasize the result of a given lister. Such links will be made available in the documentation page compiling the current statuses of available listers.
