Add test mocks and update delete API assertion

Add missing mocks used by updated code paths: mock PreferencesContext in profile page tests and add useReplaceWithTorrent/replaceWithTorrent mock for InteractiveTorrentSearchModal tests. Update Audiobookshelf API test to expect DELETE to include ?hard=1 and Authorization header. Extend the prisma test helper in audiobook-matcher tests with a reportedIssue.findMany mock and ensure it resolves to an empty array for the test.
