What problems was I solving

The PrimarySaveChangesButton component in the management UI had no production callers after the brand design workspace modernization, leaving unused code in the repository that added maintenance and bundle overhead.

What user-facing changes did I ship

No user-facing changes. The component was already unused, so removing it does not alter any visible UI or behavior.

How I implemented it

Deleted the primary-save-changes-button.tsx file and removed its barrel export from the components index.ts. A repository-wide search confirmed no remaining references to the component or its module path.

Description for the changelog

Removes the unused PrimarySaveChangesButton management UI component and its barrel export. The component had no production callers, so this is a non-functional dead-code cleanup.
