test(pdf-viewer): consolidate spec.ts into test.ts — absorb page-counter test, delete spec

Browse Source 
Absorbs the three tests from PdfViewer.svelte.spec.ts (nav buttons, zoom
controls, page counter) into the loaded-state describe in test.ts, then
deletes the now-empty spec file. One spec file per component.
