Adds MilerDutyLog, MilerBreakLog, MilerSupportTicket models and earnings
fields on BookingAssignment, plus a new milerAppController.go wiring 10
endpoints under /api/v1/miler for the rider app: duty start/end/status,
break start/end, own-bookings listing, delivery confirmation (writes
DeliveryProof, completes the assignment, publishes booking.outcome via
NATS, and pushes an FCM delivery notification), earnings summaries
(daily/weekly/monthly), synthetic notifications, and support tickets.
