Update authentication APIs to enable HybridApp auth refactor

[Julesssss]

Problem

I am working with @war-in and @staszekscp on a HybridApp authentication refactor.

They are making good progress but require some backend changes in order to complete the work.

Solution

Update backend APIs to match required onyx data:

we localized three more commands which need to return tryNewDot value

• SignInWithGoogle
• SignInWithApple
• SignInWithShortLivedAuthToken (for SAML)
  We can unify SignInWithShortLivedAuthToken and SinginUser by moving value returned by SignInUser to BeginSignIn.
  We can also simplify the frontend code and return nvp_tryNewDot in the onyxData (like we do for e.g. credentials in BeginSignIn command) so those onyx updates would be handled automatically.

Onyx Data

{
  "onyxData": [
    {
      "onyxMethod": "merge",
      "key": "nvp_tryNewDot",
      "value": {
        "classicRedirect": {
          "dismissed": true/false
        }
      }
    }
  ],
  "jsonCode": 200,
  "requestID": "8ecc27b03b9abbcf-WAW"
}

This is lower than other issues in my HybridApp queue

@Julesssss Whoops! This issue is 2 days overdue. Let's get this updated quick!

Finishing up other HybridApp tasks, I should have time for this soon after the new year

Still waiting for the ability to prioritise

The front-end work is in progress.

@war-in asked me to provide these changes. I'll be picking up this issue soon.

THis is on my todo list after a fire, and one other HybridApp backend issue.

Aiming to work on this this week!
