feat(stellungnahme): a11y, Suche, Frist-Status, Steckbrief & Map mobil

- Titel klickbar als <label> (Tastatur/Screenreader), aria-live auf Ausgabe
- Neustart mit Rückfrage, mailto-Längen-Guard (>1900 Zeichen)
- Frist-abgelaufen-Banner statt kommentarlos verschwinden
- Suchfeld filtert allgemeine Argumente live
- <details>-Chevron dreht beim Aufklappen
- Steckbrief einklappbar + scrollbar, Single-Newlines als Hard-Break
- Mini-Map responsive Höhe (h-56 mobil → h-80 desktop)
- Ausgabe-Buttons text-sm/text-[11px], mobil umbrechend; Mail-Link no-underline
- gebietsBez-Deklaration vor Verwendung gezogen (svelte-check Fehler)
