fix: Enhance layout loading logic in screen management

- Updated the ScreenManagementService to allow SUPER_ADMIN or users with companyCode as "*" to load layouts based on the screen's company code.
- Improved layout loading in ScreenViewPage and EditModal components by implementing fallback mechanisms to ensure a valid layout is always set.
- Added console warnings for better debugging when layout loading fails, enhancing error visibility and user experience.
- Refactored label display logic in various components to ensure consistent behavior across input types.
