[Design] Contractual part

[teunfransen]

Business rules contractual part

• Applications created by Institution Org Admins do not have to do contractual part (implicit that they approved) [design needed]
• Applications created by Institution Org Members need to be approved by the Institution Org Admin (Institution Org Admin needs to get a notification on creation?) [design needed]
• Applications created by External Org Admin/member always need to finish the contractual part (this process is not done yet, is with @arnoutt ) [design needed]
• Org guests have been invited for a Institiution or External app, they don't have any business with contractual part [design needed]
• App members don't have any business with contractual part (same logic as previous item)
