Refactor configuration handling in aicodebot

In the pursuit of simplicity and clarity, the configuration handling functions have been moved from `aicodebot/helpers.py` to a new file `aicodebot/config.py`. This change enhances the modularity of the code and makes it easier to manage and understand. The `cli.py` file has been updated accordingly to import these functions from their new location.
