The PR appears safe to merge because the extraction preserves the existing behavior across all reachable upload states.

Summary

This PR extracts the duplicated selected-file presentation from both knowledge-upload modals into a shared KnowledgeUploadRow component.

• Preserves file names, formatted sizes, error styling, and loading indicators.
• Preserves disabled removal behavior and the optional retry action.
• Updates both existing callers without changing their upload-state logic.
