fix(tickets): wire contact, assignees through controller + fix status type bug

- Pass contact_id, assign_users, assign_groups, custom_fields from
  controller to model on ticket creation
- Fix updateTicketStatus: getString→getInt (was passing string to int param)
- Add getBackendUsers() and getUserGroups() to TicketsModel
- Add assign users/groups multi-select fields to creation modal
