Label ticket enums server-side so clients never guess the scale

A webhook consumer read priority 4 off a ticket and called it 'Low (4)' in a
posted note — inverting Freshservice's scale (4=Urgent). Add *_label companions
(priority, status, impact, urgency) to every ticket returned by get_ticket and
list_tickets; status labels resolve through the live instance status list, so
custom statuses label correctly too.
