feat: Enhance inventory and outbound pages with category mapping and user information

- Implemented user mapping to display user names instead of IDs in the inventory and receiving pages.
- Added category mapping for materials and units in the outbound page, improving data representation.
- Updated API calls to fetch user and category data, ensuring accurate and user-friendly displays.
- These enhancements aim to improve the overall user experience by providing clearer information and better data management across multiple company implementations.
