- Added JobOrder model with ticket FK, assignedTo/createdBy user FKs
- Added orderNumber (JO-NNNN), scheduledDate, timestamps, outcomeNotes
- Added jobOrders reverse relation on Ticket model
- Added assignedJobOrders/createdJobOrders reverse relations on User model
- Applied migration: 20260304235859_add_job_orders
