test: Add statistics test with manual data insertion

- TestStatisticsEndpoints: tests /api/v1/statistics/summary endpoint
- TestPartialMigrationThenSyncThenComplete: tests migration + sync workflow
- insertTestData: helper to insert 5 soundtracks with 8 songs
- getTestToken: helper to get auth token for tests
- Updated other test files to use FindAllSoundtracks instead of FindAllGames
