Product subscription now stores tenure + total cycles

Added totalCycles and tenureInDays to product subscription schema.
Computed from customPlanEndDate + billingCycleInDays.
File: evergreen_pos_be/src/models/subscription/subscription.model.js
Product subscription cycleNumber now reflects first payment

Previously stayed 0 after first payment because invoicePaid ignores subscription_create.
Now set to 1 at subscription creation.

Product subscription completion now checks totalCycles

If cycleNumber >= totalCycles, it closes the subscription.
