Subject: [PATCH] feat: Implement copy functionality for item inspection
 information

- Added a modal for copying inspection information from a selected item to multiple target items.
- Implemented search and selection logic for target items to facilitate the copying process.
- Included validation to ensure a source item is selected and that target items are valid before proceeding with the copy operation.
- Enhanced user feedback with toast notifications for successful and error states during the copy process.
- Updated BOM management to include unit label handling for better clarity in item representation.
