feat: F4.8d the documentation mode's report as a PDF, as Java's

ReportRun reads Java's report back with iText: every piece of text with its
place, font, size and colour. The editor lays the report out by iText's
rules (A4, leading 1.5, loose chunks in the current line, tables 80 % wide
with padding 2, fixed traffic columns, page breaks) and draws it with
pdf-lib in the PDF's own Helvetica, widths without kerning as iText measures.
All device pages of Internet_Komplett, the first page and the data exchange
of einfaches_rechnernetz_komplett match Java piece by piece; Java's iText
reads our PDF with the same text in the same places. The sidebar gains
Java's "Report"; the frames come from the room by a short subscription.
Not adopted: true/false for DHCP (Java's own Ja/Nein), hash table orders,
an image running off the page, the report writing back into the model.
