Key Changes

• Redesigned interface for Singin and OTP
• Redesigned interface for Survey
• Added new app selecting interface on app management

QA Instructions

1. Sign-In: Verify that you can sign in using all available authentication methods without encountering any issues.
2. Resend OTP: Test the "Resend OTP" feature. Request a new OTP, and ensure you can sign in using the newly received code without any problems.
3. Expired OTP Test: Request an OTP and wait for 15 minutes before trying to sign in with it. The expected result is that the sign-in attempt should fail.
4. Survey Completion: Sign in with new credentials, ensure you are redirected to the survey page, and then complete and submit the survey without any issues.
5. Create New App: Use the new app selector UI to create a new app, ensuring the process completes without errors.
