Add Test User Account for Jest Tests to Avoid Using Personal Credentials

[monilpat]

Description:
To improve security and maintain best practices, we should set up a dedicated test user account specifically for running Jest tests. This will allow our automated tests to operate independently of personal or organizational credentials, reducing potential risk and improving test reliability.

Task Details:

1. Create a test Twitter account (if one does not already exist) with minimal permissions required for test cases.
2. Update the environment configuration for Jest tests to use the test account's credentials.
3. Modify relevant test setup code to pull from these credentials instead of personal accounts.
4. Ensure all tests run successfully with the new credentials.

This update will enhance our security and reduce the risk of using sensitive credentials in test environments.
