refactor: remove config file location display feature

Remove the config file location display from settings dialog to simplify
the user interface. Users who need to access the config file can still do
so through the advanced settings section.

Changes:
- Removed ConfigPathDisplay component and its usage
- Removed configPath and openConfigFolder from useSettings hook
- Removed configPath and openConfigFolder from useSettingsMetadata hook
- Removed related i18n keys: configFileLocation, openFolder
- Updated settings dialog to remove the config path display section

This simplifies the settings UI while maintaining access to config
directory management through the advanced settings tab.
