In workflows admisn display the ticket

[DonHaul]

Similar to #549

We should display the tickets inside the workflow detail page in admin.

We can achieve that by using inlines in the Admin configuration. Another example is in scoap3

Tech notes:

• Add an inline for decisions something like:

class WorkflowsTicketsnline(admin.StackedInline):
    model = Decision
    extra = 0
    can_delete = False
    show_change_link = True
    readonly_fields = [
     ticket_url,
    ]

and this should be added to WorkflowAdmin in the inlines

Acceptance:

• We have to display a list of tickets inside the workflow admin UI.
• Ensure that the user is also visible not just the user id
