GET /customer/wallet now reads the EnakPoint & EnakCoin wallet
(docs/prd-point-coin.md F6, PC-106): spendable point and coin balances, the
rupiah value of one EnakPoint and of the balance, the nearest day each
currency loses balance (grouped by Asia/Jakarta day), and recent ledger
rows. The fields of the pre-wallet response stay, filled from the wallet, so
app versions that read them keep working.
Adds GET /customer/wallet/transactions with pagination and filters for
currency, one or more types, and an inclusive date range. Each row shows
where the value came from (additions) or went to (deductions) as in §8.1,
and additions list their lots and earliest expiry. The counterparty id, the
admin and the metadata are left out; the description already carries the
masked name. A malformed query answers 400, a missing customer 404.
/customer/points and /customer/tokens keep their shape and now read the
wallet too, so customer_points_repository is no longer used for balances.
Balances are what the customer can spend: lots that have expired but that
the expiry job has not processed are not counted. The point value is read
from organization_settings (loyalty.point.value, default 1) through a small
repository that the typed settings reader in PC-109 will build on.

Adds cmd/wallet-migrate (make wallet-migrate, args=-dry-run to only report),
which moves customer_points and customer_tokens into the wallet
(docs/prd-point-coin.md §10, PC-105). Each customer gets a MIGRATION ledger
row and a non-expiring lot per currency, written through WalletProcessor in
one transaction per customer. EnakCoin is the sum of every token type (Q6),
with the legacy rows listed in the row's metadata.
It credits the difference between the legacy balance and what earlier runs
migrated, so running it again never doubles a balance and picks up only
what the old code added since. A legacy balance that shrank after being
migrated is reported and left alone, since only an admin adjustment may
take balance away, and the command then exits non-zero. It ends with a
legacy / migrated / wallet total per currency.
Migration 000092 renames TOKENS to COINS in campaigns.type and
campaign_rules.reward_type. The campaign API now validates COINS; it still
accepts TOKENS, including as a list filter, and stores it as COINS so older
dashboards keep working while they are updated.

Products like fish are sold per weighing (4.2 ons, 5.6 ons), which the
order line could not represent: quantity is INTEGER and prices are always
computed as quantity * unit_price.
Model one weighing as one order line. quantity stays INTEGER and keeps
meaning "how many items"; the measured amount goes into a new nullable
order_items.weight, and the line is priced weight * unit_price. Two
weighings of the same product are two lines, never merged into one.
Keeping quantity integral avoids float comparisons in void, refund and
split bill, where accumulated rounding error would silently misbehave —
"1.4 + 1.4 + 1.4" is not 4.2 in float64, which would leave a fully paid
split-bill item marked unpaid.
BillableQuantity() is now the single place that decides between weight
and count; every price and cost calculation goes through it. Missing one
would bill a 4.2 ons fish as a single ons — wrong money, no error.
Two database constraints back the design: a weighed line always carries a
positive weight, and its quantity is pinned to 1. The latter also makes
void all-or-nothing for weighed lines, so the row-splitting branch can
never produce a zero-weight remainder row.
Also wires product.unit_id through the API, which was previously not
settable at all, and corrects the misleading comment on the request's
unit_price field — that value has never been used; price always comes
from the database.
Design notes and the audit of every price multiplication site are in
docs/rfc-weight-based-products.md.
