# Refactor Google Mail Manager quota user handling

## Description

Added a new `getQuotaUser()` method to the GoogleMailManager class that combines the user's email with the current environment (`NODE_ENV`). Updated all Google API calls to use this method instead of directly using the email as the quota user.

This change helps prevent quota limit issues by creating environment-specific quota user identifiers, which is particularly useful when running multiple environments (development, staging, production) with the same Google account.
