Julian Pawlowski d2d07d5e16 refactor(sensors): Refactor price sensor calculations and remove unused methods
- Removed the `calculate_current_rolling_5interval_avg` and `calculate_next_hour_rolling_5interval_avg` functions from `average_utils.py` to streamline the codebase.
- Introduced unified methods for retrieving interval values and rolling hour calculations in `sensor.py`, enhancing code reusability and readability.
- Organized sensor definitions into categories based on calculation methods for better maintainability.
- Updated handler methods to utilize the new unified methods, ensuring consistent data retrieval across different sensor types.
- Improved documentation and comments throughout the code to clarify the purpose and functionality of various methods.
