refactor(ui): remove config file path display module

Remove the configuration file path information section from the main page footer, including:
- configStatus state and related functions
- loadConfigStatus function
- handleOpenConfigFolder function
- UI component showing config file path and folder open button

This simplifies the interface while preserving all core functionality.
