refactor: reorganize menu options and add config validation checks

- Extracted common config file validation into a new `check_config` function
- Renumbered menu options for logical order, with exit as the last option
- Added config checks before viewing share links, updating port, and changing Reality destination
- Removed trailing backslash and added final newline for proper formatting

This update improves code reusability, prevents errors from missing configs, and enhances menu usability.
