A translation table for the sentences that recur across the error types
and the simple accessors let the same wording be applied everywhere at
once, which both keeps the Chinese consistent and covers a hundred and
twenty-nine sites in a single pass. Routing, topology, access and the radio
frequency crates are now part of the sweep.
Running rustdoc with -D warnings found nine broken links: a misspelt
WGS84, links to methods and constants that are private or in a crate that
is not a dependency, and three redundant explicit targets. Fix each and add
a documentation step to CI so a doc comment cannot drift away from the code
it describes without the build noticing.
