Help me create a new view for directors, called directorteamview.vue. It will do the following:
1. If director, which has role == 1, has subordinates with only role 2 (staff), then it will copy how the right card is shown for managerteamview, where staff are grouped by positions.
2. If director has subordinates with role 3 (manager), then the right card will be first grouped according to the manager's name, which indicates the team. Within the card with the manager's name, it will mimick the managerteamview, where staff are then grouped by positions.
3. The calendar event should show the total count of office and wfh for all the staff in the department, exlcuding himself.

Give me the entire code, and follow the functionalities and display exactly as managerteamview for the rest of the functions.
