[AltamashShaikh]

Description:

Code to add "Reauth via SSO" in password confirmation box
Fixes: #PG-4537
Requires: https://github.com/innocraft/plugin-LoginSaml/pull/193

Logic:

1. Check if "Reauth via SSO"" is needed and set isReAuthEnabled=1
2. In Password confirmation, if isReAuthEnabled=1, add Reauth via SSO button
3. On button click, call a controller endpoint with a tempToken to get the reAuth URL
4. Open the reAuth URL in new window
5. Start polling for reAuthStatus with tempToken
6. On success, close the modal and call submit action and set tempToken as password
7. Pass the confirmPassword to check if Login.userRequiresPasswordConfirmation
8. SSO plugin checks if confirmPassword (TempToken) set in session.
