Add key information on top of dashboard

[kermitt2]

When viewing the dashboard of an entity, it would be important to display first at the top of the dashboard a small box with the key information related to the entity which informs the user about the information used to build the dashboard:

• for author: total number of publications, current affiliation (full - from lowest unit to institution), total number of affiliations in time, earliest activity - we could add current email if available

• for organisation: full name, total number of publications, total number of substructures, total number of persons, info if still active or not, earliest activity - we could add current address and web page if available
