🛠 Changes

• Reinstate TestDenyACOs_Integration

ℹ️ Context

• To use the river queue's test helpers, a pgx upgrade was required. These updates have caused tests to fail.
• PGX 5.7.1 was the previous version that did not have any issues—upgrading to any version past that introduces these errors, particularly with the lambda integration test. Since no updates are planned for the ACO Deny Lambda, we can safely allow this test to fail while we determine a fix.
• The lambda test is failing because there seems to have been a known issue in 5.7.2+ when trying to scan a nil *struct, which is what the test is doing.
• This is a known issue that was addressed here and fixed here
