Implement Email Tracker Feature

[rukaiah-edhah]

User Stories:

1. As a user, I want to link my sign-up email to the application so that my job-related emails can be tracked.

• Integrate the email API to use the user's sign-up email for tracking communications.

2. As a user, I want the application to monitor and log emails sent to companies, so I can keep track of my communication history and see the status of my emails (sent, received, read) within the application.

• Develop functionality to track and log emails, including their status.
• Update the database schema to store email statuses.
• Implement a frontend component to display these statuses for each job application.
