Add email verification service layer #119247

[Diana20920]

Summary

• This work is behind a feature toggle (flipper): NO
  • The controller what will be added and will be calling this service will use the existing feature toggle (flipper)

This adds the EmailVerificationService, which contains the core logic for verifying a user’s email. The controller calls this service to start and complete the verification process, and the service triggers emails to the user when the process begins and when it completes successfully. Logging has also been added for visibility. Remaining components of this work will be integrated later, and this service may be updated as needed.
