Drei Aufbauten fuer neue Beitraege

Umut wollte mehrere Designs zur Auswahl. Bei Seiten waere das falsch -
dort weiss vorher niemand, was daraus wird. Bei Beitraegen ist die Form
fast immer dieselbe, und wer jedes Mal von vorn anfaengt, baut jedes Mal
etwas leicht anderes.

Bildkopf (Bild ueber die volle Breite, Titel darauf), Klassisch (Titel und
Vorspann schmal, Bild darunter) und Magazin (Titel neben den Eckdaten).
Gewaehlt wird beim Anlegen; danach ist jeder Block aenderbar wie jeder
andere. Kein Aufbau verlaesst sich auf ein Bild, das es noch nicht gibt.

Dabei ist eine Regel gefallen: der erste Textblock eines Abschnitts wurde
automatisch zur Kleinbeschriftung in Akzentfarbe. Das gestaltet nach
Position statt nach Absicht - im Fussbereich wurde daraus roter
Versalientext, in der Magazin-Vorlage aus dem Einstiegsabsatz eine
Beschriftung. Wer eine Beschriftung will, stellt sie ein.

Geprueft: 398 Tests unter PHP 8.2 und 8.4, Editortest, Browserpruefung,
axe ohne Verstoss auf allen drei Aufbauten.
