refactor: improve readability and error handling in install_config.sh

- Refactored the code to improve readability by adding bold formatting to console output.
- Improved error handling by using the exit status of commands instead of a separate variable.
- Replaced repetitive sleep calls with fn_sleep_time function.
- Updated log messages for clarity and consistency.
- Added conditional checks for successful file copying and printing appropriate status messages.
