Fix all Vitest test failures after migration

- Replace vi.mock('axios') with nock for HTTP request mocking (ES/CJS interop issue)
- Fix RTorrentClient by mocking client.client.methodCall directly instead of xmlrpc module
- Fix downloadClients.test.js by manually adding mock clients to registry
- Fix qbittorrent.test.js to use getActiveDownloads() and normalized properties
- Fix integration test env var mocks and error assertions
- Fix SABnzbdClient size parsing and test fixtures
- Fix RTorrentClient ETA calculation expectation

All 261 tests now passing.
