- use-admin-hooks: LedgerOverview.journal, LedgerEntryRow,
  LedgerSellerDetail journal fields, useLedgerJournal.
- new "دفتر روزنامه" sub-tab + admin.ledger.journal route.
- ledger overview: journal-derived KPI row + recorded-vs-journal drift badge.
- seller detail: journal-balance stat + journal history table.
