fix(current-accounts): show bank/branch letterhead on passbook, matching savings

Current account passbook hardcoded "LincPay Co-operative Bank Ltd." and had
no branch identification line at all, unlike the savings passbook which
pulls the bank name and branch/IFSC/MICR details from the Institution and
Branch Profile. Wire up the same OrganizationService lookup so the current
account statement shows real bank/branch details too.
