refactor: Update logger initialization and configuration

This commit updates the `log.go` file to improve the initialization and configuration of the logger. The code changes remove unnecessary comments and unused variables, ensuring cleaner and more efficient code. Additionally, the `load` function is modified to properly handle errors when loading the logger configuration file. These improvements enhance the overall functionality and maintainability of the logger module.
