chore: genericize the remaining adopter package prefix in the C# port

A first pass matched only the `::api` and bare-value forms and missed `::common`
and `::reporting` in two C# files. Both now use the `acme::` convention already
used by the neighbouring tests in the same directory.

Build succeeds with 0 errors and the affected test passes.
