feat: optimize file icons, UI, share direct links, and upload performance

- Replace CSS-only file icons with SVG icons for each file type (folder, image, video, audio, archive, document, app)
- Add navigation icons to left sidebar (Baidu Netdisk style)
- Enlarge file cards (108px -> 120px) with smoother transitions
- Add direct links section to share page with copy/delete actions
- Add Rust bridge commands for fetching and deleting direct links
- Optimize local storage put() to use rename-first strategy instead of copyFileSync for instant large file completion
- Show "server processing" status during upload finalization instead of appearing stuck
