Enhance EquipmentLive.Show test coverage with additional test cases

Added 5 new test cases for EquipmentLive.Show module:
- Test with tab parameter (interfaces tab)
- Test equipment status with monitoring checks
- Test SNMP device information display
- Test recent events display
- Test handling of missing equipment

Coverage improvement: ToweropsWeb.EquipmentLive.Show 35.51% → 46.38%
Overall coverage: 59.88% → 60.40%

All 21 tests pass successfully.
