Add feature to Copy Affiliation

Is your feature request related to a problem? Please describe.
To facilitate the change of current affiliations it should be possible to create an affiliation based on the information of an already existing affiliation. This might be required when a typo occurs or an address addition should be added to an organization.

Describe the solution you'd like
It should be possible to create a new affiliation based on an already existing affiliation (copy the affiliation)

Additional context
Consider adjusting the current CreateAffiliationView in a way that all fields are pre-filled after an organization is selected.
