#268 - related reported issue

NGO Admin user should be displayed in the Staff section but marked distinctively:

• The profile should be accessible only to them and other ngo admin users
• For the other specialist users who have access to the Staff section (due to the additional permissions) the "Vezi detalii button should be disabled
• In the Echipa interdisciplinară table, the NGO Admin users should be marked as depicted in the design (link)
