* CENTRAL EMAIL COMPOSER COMPONENT
*
* This is the unified, centralized email composer component used throughout the application.

*
* All code that needs to compose emails should import this component from:
* @/components/email/ComposeEmail
*
* It uses the centralized email formatter from @/lib/utils/email-formatter.ts
* for consistent handling of email content and text direction.
