Create healthcare providers list page

[vlad-ignatov]

• Should list several healthcare providers with their names and logos (and perhaps a short description?)
• They should act like links but all except one should be disabled and probably greyed out
• The one item that is not disabled should start an EHI export against our server
• Items only serve as visual example so they can be hardcoded. However, in the future they might need to be obtained by an HTTP call, thus it would be better if we declare them in a variable for now (array or object) and use that to render the list
