Add singleton logging configuration for the renamer application

This commit introduces a new module `logging_config.py` that implements a singleton pattern for logging configuration. The logger is initialized only once and can be configured based on an environment variable to log to a file or to the console. This centralizes logging setup and ensures consistent logging behavior throughout the application.
