Show the person card in donation creation and edition when selected from the people list

[hundrex]

Context

When creating a donation, we have a list of people to select for the donator, but when selected, nothing happens. It would be great to show the person card in a similar manner than what has been done for the memberships.
Moreover, the card shows up when we first edit a donation, but if we click the "replace" button, it disappears, which makes it even more strange that it does not shows again when selecting an other person.

Todo

• add a way to show the card when a donator is selected on the donation creation page
• add a way to show the card when a donator is selected on the donation edition page
