ZCU-PUB/fix: split merged providers in file-download-link spec (TS1117) (#1401)

The FileDownloadLinkComponent spec declared both providers in a single
object literal, so the second `provide`/`useValue` pair overwrote the
first. TypeScript flagged this as TS1117 (duplicate object key), failing
the spec bundle compilation and blocking the entire `test:headless` run.

Split into two separate provider entries so both AuthorizationDataService
and DSONameService are registered. DSONameService is required: the
component injects and uses it (file-download-link.component.ts).
