[ADD] mail, mass_mailing: allow a user to resend a mail with failures

When a mail is in failure state, a red envelope appears next to the message
in a thread but it was difficult to send the mail again.
This tasks will allow users to send mail again easily, or mark notification
as cancelled if the user want to ignore this failure.
A notification will appear in sender systray while mail are in failure.

Task: #46158
PR: #24628
