BE Show security policy dismissals in vulnerabilities column of dependency list

In the dependency list, we want to show security policy dismissals in the vulnerabilities column when a dependency has vulnerabilities that match a dismissed policy. This provides users with visibility into which vulnerability findings have been dismissed through security policies.

Background

This is the second part of showing security policy dismissals in the dependency list. The first requirement (showing dismissals in the license column) is being addressed in #562185.

Design

The data source for the dependency list page is the getProjectDependencies GraphQL endpoint
