feat: add EngineMaxTemperature support for diesel locomotive overheat detection

Browse Source 
Add engine temperature monitoring to diesel locomotive heat management system:
- Add engine field to heat_data struct (fluid_circuit_t type)
- Add EngineMaxTemperature config extraction in .fiz files
- Add engine overheat detection logic (is_hot check)
- Include engine.is_hot in PT status check

Implements issue #77: Oil, water and engine overheat lamps for diesel locomotives
