feat: add top navbar to /share page, move nav links out of upload zone

- Add NavBar component with app branding and conditional nav links
- NavBar shows "个人中心" for token_manage permission, "管理控制台" for user_manage
- Restructure share.tsx with flex column layout (NavBar + 3-column grid)
- Clean up panel-left.tsx: remove auth check, nav links, and unused styles
