feat: TUI als Browser-App via textual serve

TUI von direkten Service-Importen auf httpx API-Calls umgestellt.
Neue tui/api_client.py als schlanker async HTTP-Client. Background-
Worker pollt API alle 5s für Echtzeit-Updates. Neuer tui_standalone.py
Entry-Point für 'textual serve --port 8001 tui_standalone.py'.
