feat(cashier): morning opening balance panel across settlement, reconciliation, position & history

- Cash Settlement form: morning panel (denomination pills) + Morning column in denomination table
- Reconciliation form: morning panel (denomination pills) + Morning column in denomination table
- Cashier Position Report: Morning vs Current comparison bar + Morning column (single-cashier mode)
- Cash History – Settlement detail panel: Morning Received vs Settled comparison bar + Morning column
- Cash History – denomination Notes/Coins separation in detail panel for all transaction types
- CashierService: added getCashierMorningBalance() calling GET /cashreports/cashier-morning
- All morning data loaded via forkJoin alongside existing API calls (no extra loading states)
