refactor: improve logging and error handling in install_config.sh

- Refactored the code to use more descriptive function names.
- Improved logging by using fn_print_ok_eol and fn_print_failure_eol functions.
- Added error handling for copying config files, displaying failure messages if necessary.
- Updated comments for better clarity.
