EvFallbackStrategy
Defines the strategy to apply when EV data is missing or invalid.
This is used to determine how the system should behave if required EV-related inputs (like stateOfCharge, efficiency, or chargingCurve) are missing, null, or malformed.
There are two standard fallback strategies:
FallbackToRegularNavigation — gracefully degrades to standard navigation mode and logs missing data.
CrashOnError — immediately throws an error when invalid or incomplete EV data is detected.
