Merged PR 5364: Outstanding Payments

# Description

Adds a field that helps categorize whether we owe money to an account or they owe money to Truvi.
Outstanding Resolutions or Outstanding Invoices

The idea is to include this field as a filter in the Invoicing & Crediting report to help Finance and Resolutions in the payment and approval process.
