Comprehensive Test Suite for Action-based CampusLifeBench System

This test suite validates all aspects of the new Action-based system including:
- Single-system tests for all 10 subsystems
- Multi-system composite tests
- Ultra-complex integration tests
- System availability validation
- Temporal Week 1 simulation
- Action format validation
- End-to-end LAB framework integration
