refactor: Simplify average calculations in Detail component

- Streamlined the calculation of average RPM and average TPM by removing unnecessary function calls and directly applying the `toFixed(3)` method within the JSX.
- Improved code readability and maintainability by reducing the number of lines and enhancing clarity in the calculation logic.
