- Fix TestKoboInitialization: use setupDeviceTest() for device creation
- Fix TestKoboLibrarySync: remove /test-token/ route path, add device auth
- Fix TestKoboMarkupSync: add device auth and last-read-place test case
- Fix TestKoboBookmarkSync: add device auth and last-read-place test case
- Fix TestKoboAnalyticsGettests: add device authentication
- Add debug logging to all test functions
- Remove unused imports (config, database, middleware, router, services, sync)
Phase 3 of KOBO_IMPLEMENTATION_PLAN.md completed (Steps 7-12).
All tests now use proper device authentication (Bearer tokens + x-kobo-device headers)
and include test cases for the new last-read-place bookmark feature.
