Adds earning reversal (docs/prd-point-coin.md F10, Q3, PC-204).
VoidOrder, RefundOrder and RefundPayment now end with an onOrderRefunded
hook, called once their writes have committed and, like onOrderPaid,
detached from the request so it can never block or fail the void or
refund. For RefundPayment that is after its transaction.
EarningProcessor.ReverseForOrder computes how much of each EARN row should
have come back in total: everything for a void, otherwise
floor(earned × refunded / basis) with the order's cumulative refund and
the basis frozen on the EARN row, never more than was earned (a refund
including tax can pass the basis). It takes only what has not been asked
back yet, what was taken plus any shortfall, so repeats and successive
partial refunds never add up to more than the earning. It writes an
EARN_REVERSAL pointing at the EARN with DebitUpTo, drawing from the lots
the EARN created first, and records the shortfall when the balance was
already spent.
When the balance is empty there is no ledger row to carry the shortfall;
that case is logged. VoidOrder still refuses fully paid orders, so a void
has nothing to take back today; the hook keeps it correct if that changes.

Adds earning at payment time (docs/prd-point-coin.md F3, PC-203).
An order becomes fully paid through UpdateOrder, CreatePayment and both
kinds of split bill. All of them now go through one OrderProcessorImpl
hook, onOrderPaid, called after the payment has committed; for
CreatePayment that is after its transaction, not from updateOrderStatus
inside it. The hook runs detached from the caller's transaction and from
the request being cancelled, and it runs synchronously so the order
response can show what was earned.
EarningProcessor.EarnForOrder skips orders that are not paid, are void,
have no customer, or whose customer is the walk-in customer or inactive.
It computes the earning with CalculateEarning, subtracting any part paid
with EnakPoint (none until phase 3), and credits each currency through the
wallet engine as EARN with key earn:{order_id}:{currency} and the settings
snapshot in metadata. A repeat, even concurrent, credits nothing more.
OnOrderPaid never fails the payment: errors and panics are logged.
EarningBackfillJob is the safety net: every 30 minutes it earns for orders
paid in the last three days that have no EARN row. It only looks at
outlets with earning switched on and pages by (updated_at, id), so orders
that correctly earned nothing cannot starve the ones that were missed.
Lots from earning never expire until the expiry model is decided (F12,
note N4). Adds the point payment method type constant, not yet accepted as
a payment method.
