feat(cashier): add full-screen cashier teller workstation dashboard

- Add Transaction Entry screen with full account details panel
  (personal info, joint holders, nominees, KYC, balances)
- Role-based layout: CASHIER role hides nav/sidebar/ticker,
  redirects to /cashier/transaction-entry on login
- Denomination entry with opening/closing position preview
  (notes first then coins, stepper +/- round button inputs)
- Auto-fetch savings/current/FD/RD accounts with associations,
  client KYC, nominees, addresses, family members (S/D/W/H/O)
- Submit deposit/withdrawal via POST /transactions with denominationBreakdown
- Cashier position auto-loads for CASHIER role (no filter dropdowns)
- Pagination added to cash-history tabs and currency-exchange-detail
- Cashier menu simplified for cashier role permissions
