feat: Stream-Abbruch per Stop-Button

- Neuer Stop-Button (#stop) neben Send-Button, erscheint nur während Stream
- AbortController in chat.js: abort() schließt SSE-Verbindung → Backend CancellationToken triggered
- apiChat() akzeptiert optionales AbortSignal
- AbortError-Handling: zeigt 'Abgebrochen' statt Fehlermeldung
- Button-Toggle in sendMessage(), stopStreaming(), startStreamingPoll(), Page-Load-Recovery
- CSS: .stop-btn mit --dangerous Farbe
- Diverse kleine UI-Fixes (TODO.md, theme.css box-spacing, settings-section Layout)
