feat(cashier): cashier-only cash operations, exchange PAN/denomination checks and Branch Cash Position

- Cash Exchange Entry: customer details with PAN (mandatory above Rs 50,000), cashier card,
  denomination-wise validation against the master and real-time impact preview.
- Inter-Cashier Transfer: sender fixed to the logged-in cashier, both sides' details and
  denomination holdings shown, blocked until both are allocated cash.
- Reconciliation, exchange and inter-cashier operate on the logged-in cashier only.
- New Branch Cash Position screen (vault + cashier drawers, denomination-wise).
- Customer search dialog shows the KYC PAN.
- Cashier menu cleanup: Excess/Closing report and Exchange Detail removed, nav compacted to one row.
- Reverse actions removed from cash transfer, settlement, exchange and inter-cashier.
