Authentication Integration

• A new SignIn.page.js file should be created under the app/pages folder
• A new SignUp.page.js file should be created under the app/pages folder
• A new RequestPasswordReset.page.js file should be created under the app/pages folder
• A new ResetPassword.page.js file should be created under the app/pages folder
• A new file with name authentication.queries.js should be created under app/graphql folder
• This file should contain all the queries, mutations and subscriptions (schemas) needed for the SignIn page like:
  • e.g. login, signUp, sendPasswordResetEmail, resetPassword e.g. (https://gitlab.coko.foundation/hhmi/hhmi/-/blob/master/packages/client/app/graphql/authentication.queries.js)
• SignIn.page.js, SignUp.page.js, RequestPasswordReset.page.js, ResetPassword.page.js should take advantage of useQuery and useMutation from @apollo/client for the execution of the above queries

Until the actual UI become ready the SignIn.page.js, SignUp.page.js, RequestPasswordReset.page.js, ResetPassword.page.js should return a dummy div.
