Screen value (mobile number) is not visible in the UI for Federated SMS OTP connector

[JayaShakthi97]

Describe the issue:

When trying SMS OTP flow with Federated SMS OTP connector, the screen value is not visible in the UI even though the configurations are added.

How to reproduce:

1. Setup federated SMS OTP through the management console. (You have to enable the identity providers menu)
2. Add it to an application's login flow as the second factor.
3. Add the following config to the deployment.toml

[authentication.authenticator.sms_otp.parameters]
screenUserAttribute = "http://wso2.org/claims/mobile"
noOfDigits = 4

4. Restart the server and try login flow with the application.
5. Observe the OTP verification page.

Expected behavior:

Masked mobile number should be visible in the OTP verification page.

Analysis

• In smsOtp.jsp, it is looking for the query param named screenValue[1]. This is expected for local SMS OTP authenticator.
• But for federated SMS OTP connector, the query param should be screenvalue[2].
• SMS OTP page should be updated to support both.
