[NGO Admin/ Cazuri/ Echipa caz] update "Adauga echipa de caz" field/flow

[teodoranegru]

In the "Adauga/Modifica specialist in echipa" screen, the first field of the screen should be "Rol în echipa de caz" and the second field should be "Nume specialist"

FLOW:

1. User clicks on "Rol în echipa de caz" field
2. The system retrieves the list of all the roles in the organization (all the roles that have been linked to users)
3. User selects a role (single select field)
4. User clicks on the "Nume specialist" field (it is mandatory to select a value in the "Rol in echipa de caz" field to display any value in this field)
5. The system retrieves the list of all the users that have that role
6. The user selects a user/name (single select field)
7. The user clicks on the "Salvează" button
8. The system saves the changes and adds the user in the case team
9. The system offers access to the case to that user (if they don't already have access to all the cases in the center)

Business rules:

1. The user can add in the case team only one member at a time
2. The fields should include the search function
3. If an user has already been added to that case team, disable their name in the "Nume specialist" field and make it grey)
