Refactor client side football data

Revisit the data returned by `football/api/match-nav/` and evaluate whether it can be made more compact. 

The scorer data also needs improvement, it currently returns all information as a single string (e.g., `Rasmus Højlund 57 Pen`), which should ideally be structured into separate fields.
