Implement home screen such that it can fetch all event from the repository

[armouldr]

The frontend (the home view) needs to be able to get all events from the backend of the events (view model + repository) to display it. This means on load :

• Request the events to the view model that will request to the repository all events stored in the database
• After receiving the events, show them and, if needed, update the list is there is some change
