Improve email status labels

[andersonjeccel]

Description of the problem

Enhance the email status labels to provide clearer and more informative information about the status of emails within the system.

Users feedback:

Scheduling an email: What is published/unpublished? Why do I need to set an unpublished date for segment emails (not a common way to send out emails, even though the function is useful once the customer understands it). Why is "scheduling" called "publishing" for segment emails?

"Scheduling an email is called "scheduling" and not "publishing" and it's not the same thing as "keep sending the email to a segment until a certain date"

Impact

Improving email status labels will lead to better user understanding, more efficient email management, and reduced confusion, ultimately contributing to a more effective email communication system.
