Improve animation flows and video metadata

[han4wluc]

Summary

• replace the animation type context menu with an add dialog that collects name, description, and type before opening the editor
• add animation duplication support through the resource command API and file explorer integration
• carry video duration through upload processing and show it in the videos detail panel
• keep a few related UI polish updates, including tighter line icon spacing in the scene editor
