Restructure queries so phpcs rule passes
Restructure query code so that the WP linters for prepared queries passes. The linters are extremely primitive and only pass if we write the code in a very specific way. In a lot of cases such as working with multiple rows or values, it is impossible to satisfy the linter. In those cases, we add an ignore rule inline. All the code was already prepared correctly, so this doesn't change any behavior. It just satisfies the linter.
