Stadionzeitung, Veranstaltungen, News-Artikel, Lightbox und Anzeigen-Verteilung

Stadionzeitung: Live-Seiten (Tabellen, Ergebnisse, Vorschau, Termine, News,
Kontakt, Historie, Sportheim, Partner, Momente, Impressum), automatisches Cover,
Swipe-Viewer mit Vollbildmodus und die Druckfassung als Falt-Heft. Anzeigen
kommen jetzt aus dem Bestand und werden gleichmäßig verteilt, nie mehr als zwei
hintereinander (vorher vier Blöcke à fünf). Die Doppelseiten-Regel rechnet das
Skript selbst, statt sie von Hand zu prüfen.

Veranstaltungen: Bereich /veranstaltungen mit Detailseite pro Fest, Lebenszyklus
über das Datum (Ankündigung vor dem Fest, Rückblick danach), Galerie mit
Lightbox. veranstaltungen.json ist dritte Termin-Quelle, damit ein Fest nie
doppelt gepflegt wird.

News-Artikel als dritte dynamische Prefix-Route, gemeinsamer detail-head.

Behobene Fehler:
- Wappen-Kontexte setzten Zeilen-Layout auf .crest statt auf die Zeile; das
  Wappen wurde zum Grid, Vereinsname und Tore rutschten darunter zusammen
  (Ergebnis-Rückblick, Vorschau, Cover).
- --header-h (60px) unterschätzt die Kopfleiste um 32px (Logo 72px + 20px
  Versatz): neues abgeleitetes --header-space, sonst klebten Zurück-Links
  unter dem Logo.
- base_url in der Produktions-Config ohne www, während .htaccess auf www
  umleitet; preflight prüft das jetzt.
- .lightbox brauchte display:none mit (0,2,0), sonst lag das Overlay offen.

Neue Werkzeuge: bin/anzeige-add.php (Anzeigen-Bestand), bin/veranstaltung-bilder.php
(Plakate und Galerien, Alt-Texte folgen der Quelldatei), bin/qr.php (Druck-QR mit
Warnung, wenn base_url nicht auf die echte Domain zeigt).
