feat(wallet): serve customer balances and history from the wallet

Browse Source 
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.
