- Updated the FalukantService to include additional attributes for directors, such as knowledges and region.
- Enhanced the DirectorInfo component to display detailed information, including knowledge and income management features.
- Implemented tab navigation in BranchView for better organization of director, inventory, production, and storage sections.
