Looks good to me, tested with English and German locale (for German "Config" is actually translated to "Konfigurationsdatei".
I noticed one issue in the `Tools->Configuration Files->Filetype Configuration`menu, there is `filetypes.conf` listed under `K` which might be unexpected.
So, I'd also vote for making those five filetype names untranslatable and rename them accotding to the suggestion in https://github.com/geany/geany/pull/3977#issuecomment-2481384893.
