feat: add multi-tab terminal with SSH support, config editing, and dashboard redesign

- Terminal: multi-tab sessions, SSH connections, shell detection (zsh/bash/fish/wsl/powershell)
- Config: inline profile & provider editing, system update management
- Dashboard: grid layout with inline tools/notifications/workflows sections
- Add lucide-react icons, i18n keys (FR/EN), and new CSS components
