Update email links to use sign-in page instead of careers page

Changed all email template links from https://www.codebility.tech/careers to https://www.codebility.tech/auth/sign-in for better user experience and direct access to authentication.

This affects:
- Test reminder emails
- Onboarding reminder emails
- Passed test notification emails
