feat: implement smart factory log transmission and enhance rack structure patterns

- Added a new utility function `sendSmartFactoryLog` to transmit user access logs to the smart factory logging service upon successful login, ensuring non-blocking behavior.
- Integrated the smart factory log transmission into the `AuthController` to log user access asynchronously.
- Introduced pattern utilities for generating location codes and names based on configurable patterns in the rack structure components, improving flexibility and maintainability.
- Enhanced the `RackStructureConfigPanel` to allow users to define custom patterns for location codes and names, with real-time previews and a list of available variables.
