The charger rate displayed in the vendor sessions/revenue screen is not consistently correct when multiple rate fields are available. Currently, the system directly uses energy_rate, which can lead to incorrect or null values in scenarios where ocpi_energy_rate (markup rate) is present.

To ensure accurate pricing, the charger rate should follow a fallback logic:

Use ocpi_energy_rate (markup energy rate) if available
Otherwise fallback to energy_rate
If both are null, default to 0
