Improved on invoice selection UX and add CUB logo

[ajain244]

Summary

Unpaid Invoices modal : constrain dialog to viewport (max-h-[90vh]) with a scrollable body and sticky footer so the action bar stays visible on long lists.
Row selection: support shift-click range selection, make the whole row toggle the checkbox, and ignore clicks on inner links so navigation still works.
City Union Bank: add City_Union_bank.svg asset and register it in BankReconciliation/logos.ts (keywords: City Union Bank, CUB).

Test plan

• 1. Open Record Payment → Get Unpaid Invoices on a party with many invoices; confirm the dialog doesn't overflow the viewport and the footer stays pinned while the list scrolls.
• 2. Click anywhere on a row to toggle selection; verify clicking the invoice link still navigates without toggling.
• 3. Select one row, then shift-click another — confirm the range is selected; shift-click again on a selected row to deselect the range.
• 4. Verify the totals (Invoices count / Total amount) update correctly and Cancel/Submit work.
• 5. In Bank Reconciliation, confirm a "City Union Bank" / "CUB" transaction shows the new logo.
