Display reminder validation history in the ticket's "Validation" tab

Currently, it is not possible to view the history of reminder validations and follow-ups directly within the Validation tab of a ticket.

It would be useful for this tab to display a history, including the date of the last reminder, or alternatively, add a follow-up in the ticket to indicate that a reminder has been sent.
The displayed information should include at least:

• Date and time of each validation

• Email of the recipient
