Fix Phase 2 tests: Use fake driver and IDisposable pattern

Browse Source 
- Updated all tests to use app.Init("fake") instead of Init() without driver
- Implemented IDisposable pattern with GetApp() helper for proper cleanup
- Refactored tests to use app.Begin/End instead of blocking app.Run
- Fixed type issues (SessionToken vs RunnableSessionToken)
- 9 of 16 tests now pass; 7 lifecycle tests need further refinement
