feat(cashier): add CBS Blue Warm Stone theme, validations, non-individual support, and custom alert modal

- Replace table grid with ws-wrap card-form layout (Warm Stone / CBS Blue design)
- Add day-status blocking banners (previousDayUnsettled, morningTransferReceived)
- Add custom styled alert modal replacing browser alert() — error/warning/info/success types
- Add Non-Individual Account Details section with Partners table (click-to-view signature/image)
- Fix denomination overdraft inline alert in Closing Position panel
- Fix bannedEntityMatch/willfulDefaulter false positive (DB stores YES/NO strings)
- Fix denomination mismatch 403 — only send denomination when cash payment matches amount
- Fix Today's Activity for CA accounts (m_current_account_transaction, remarks column, type=7 label)
- Fix A/C TYPE [object Object] — map from acTyp label
- Fix charge deduction sign — use transactionType.deposit instead of withdrawal
- Remove Add Row buttons everywhere
- CBS Blue theme variables: focus #2563eb, accent #e87722, Hanken Grotesk + Newsreader fonts
