feat(Localization, User Management): add missingUserId translations and enhance user ID handling

- Added translations for the "missingUserId" key in multiple languages to improve user feedback when user ID is not available.
- Updated the user ID handling in the store and WorkerSchedulesView component to ensure proper user identification when sending data to the daemon.
- Enhanced error handling to notify users when the user ID is missing, improving overall user experience.
