[Frontend] Expand search results

[FStriewski]

User story

As a user I want to be able to select (indivdual) datasets so that I get all of the properties

Acceptance criteria

• [ ] Selecting a single dataset reveals the full api response

Considerations

• We should think carefully how users might interact with the data. Some ideas:

  1. User browses the data and does spot checks on some datasets out of curiosity (or to refine search terms)
  2. User compares two or more specific datasets to decide which one to use (e.g. because of their similiarity)
  3. User selects multiple datasets in order to download all of them (e.g. because they thematically belong together)

• A separate getDataById request should be avoided, as it will impact the smoothness of the frontend and because data volume is small enough to get all values with the getData request (especially if we add pagination)
