Summary

This pull request introduces email notification functionality for key user actions and adds support for storing user email addresses. The main changes include integrating the Resend email service, sending notifications when new accounts or reviews are created, and updating the account and review creation flows to support these features. Additionally, the GitHub OAuth scope and user data fetching have been enhanced to retrieve email addresses.

Email notification integration:

• Added EmailService class to handle sending notifications for new accounts and reviews via Resend, including configuration checks and email formatting.
• Introduced new environment variables (RESEND_API_KEY, SENDER_EMAIL, ABUSE_CONTROL_EMAIL) for email service configuration in .env.example and settings.

Account and review creation enhancements:

• Updated account creation flow to fetch and store user email from GitHub, and send a notification when a new account is created.
• Modified review creation/updating flow to return a tuple indicating if a review is new, and send a notification email for new reviews.
