feat: Enhance Wails desktop app key handling for page reload

- Introduced a check for Wails desktop environment to conditionally intercept Cmd/Ctrl+R key presses, preventing full page reloads that could lead to a white screen.
- Updated event listener management to ensure key handling is only active in the Wails desktop context, improving user experience by maintaining application state during refresh actions.
- Added comments for clarity on the purpose of these changes and their impact on different deployment environments.
