Email parsed data endpoints

Two new read-only apps API endpoints are now available, allowing external systems to retrieve the parsed contents of an email interaction. This includes the sender, recipients, subject, body, and attachment metadata. Here are the endpoints:

• /apps/api/v1/email/sessions/{email_support_id}: Returns a summarization of a session and lists its messages. • /apps/api/v1/email/messages/{email_thread_id}: Returns the full parsed content of a single message.
