Adding default scopes for new API clients

We have expanded the default scopes when creating new api clients to make it easier to get started with our API! 🎉

• Accounts details (sort code/account number)
  • accounts_details:read
• Beneficiaries
  • beneficiaries:read and beneficiaries_detail:read
• Standing orders
  • standing_orders:read and standing_orders_detail:read
• Auth requests API
  • auth_requests:read and auth_requests:write
