fix(i18n): resolve missing translation keys and complete multi-language support

- Add missing keys 'common.cancel', 'common.confirm', and 'sidebar.dragDrop.noDragState' to en.json
- Synchronize all locale files using sync_translation_keys.py
- Complete translations for zh-CN, zh-TW, ja, ru, de, fr, es, ko, and he
- Implement sidebar drag-and-drop folder creation with visual feedback and input validation
- Optimize MoveManager to use resetAndReload for consistent UI state after moving models
- Fix recursive visibility check for root folder in MoveManager
