Admin texts can now contain the placeholder {{USt-IdNr}}. Wherever
content is read (lib/content.ts), it is replaced with the VAT ID
maintained under Admin > Einstellungen > Firmendaten, so every text
follows a change automatically. The placeholder is matched case- and
space-insensitively; an empty VAT ID inserts nothing, and unknown
placeholders stay visible so typos show up. Images, videos, select
fields and the source field itself are never rewritten.
The default imprint text uses the placeholder instead of a hard-coded
number, and the settings page lists the available placeholders.
