Task-2695901

Helpdesk tickets now use a configurable numbering sequence instead of only a fixed increasing ticket number. This lets businesses adjust ticket ID formatting to better match their internal processes and customer communication needs.

PURPOSE:

In helpdesk, ticket UUID is an increasing numerical value. For Ex: if your ticket
was the nth ticket submitted, the ticket's UUID would be Ticket (#n). For
businesses, this turns out to be a problem for a few reasons. One of the reason
is if user wants to re-format their ticket's UUID they cannot.

SPECIFICATION:

Add a sequence for helpdesk tickect to allow users for the customization of the
number and format of the ticket id.
