Mobile API Workflow Execution Tests

Tests for mobile API workflow execution endpoints:
- Workflow creation
- Workflow skill addition
- Workflow execution
- Workflow DAG validation
- Workflow execution history

All tests use API-first approach with TestClient (no browser).
Response structure matches web API for consistency.
