fix: profile import file upload, startup health check, sidebar scroll, node-pty fallback

- Change profile import from server path input to browser file upload (multipart)
- Fix startup script to wait for health check before opening browser
- Add overflow scroll with hidden scrollbar to sidebar nav
- Graceful degradation when node-pty fails to load (WSL compatibility)
- Remove rename button from profile cards
- Restrict profile name input to English letters, numbers, hyphens
- Use raw.githubusercontent.com URLs in README setup script
