Operator + Platform | Vehicle range budget attributes

[tom-ioki]

This pull request adds new attributes related to vehicle range budget management to both the operator and platform Vehicle models. These changes enable the system to handle information about a vehicle’s range budget, including its maximum and current values, unit, and the calculation method.

Vehicle Range Budget Enhancements:

• Added maximum_range_budget and current_range_budget integer attributes to the Vehicle model, available for create, read, and update operations. [1] [2]
• Introduced range_budget_unit and range_budget_calculation_adapter_name string attributes to the Vehicle model, also available for create, read, and update operations, with logic to omit them if nil during create and update. [1] [2]
