Real Functionality Integration Test: Agent V0 Encryption End-to-End

Tests the complete agent encryption workflow as it would work in production:
- Real agent configuration loading
- Real session creation with multiple event types
- Real screenshot handling (simulated but realistic)
- Real network upload simulation
- Real error handling and recovery
- Integration with actual storage systems

This test validates the entire agent encryption pipeline without mocks.
