* Naming: align the Chinese decorative text term

avoids GridCraft's own chart word Diagramă. A catalog test checks every
shipped language translates both labels and that Diagram differs from
Chart/Charts. The display-name guard now handles escaped char literals
and any #[cfg(test)] item, asserts it scanned catalog.rs and a minimum
of files and literals, and tests word boundaries. The catalog test
asserts each ID appears once. Docs carry timestamps and revision history.
