Enhance Space Management Features with Tag Assignment Improvements:

- Introduced UUID for ProductAllocation to ensure unique identification.
- Refactored AssignTagsDialog to manage tag assignments and validation more effectively, including error handling for empty tags and duplicate tag usage.
- Updated AssignTagsTable to support dynamic product allocation management and improved UI interactions.
- Enhanced AddDeviceTypeWidget to maintain selected products and handle increment/decrement actions, improving user experience during device type selection.
- Added AssignTagsErrorMessages widget for better error visibility in tag assignment process.
