Append a two-column signature block (Receiver/Date on behalf of the
customer, Issuer/Date on behalf of the company) after the Bank Account
Details section.
Add the "Default Standard Sales Invoice" Print Format fixture and the
Property Setter that makes it the default for Sales Invoice.
The format reproduces Frappe's standard layout and appends a Bank Account
Details section on the last page when the company has an enabled Bank
Account flagged Is Company Account + Is Default Account
(get_company_bank_account jinja method).
