Caught by an independent follow-up review: the FTP auth-bypass fix in
6b9c7cf only gated /api/fetch/lvgmc/stations, the one route the original
security review named. This sibling route calls the same fetch.fetchFile,
which opens a real, unauthenticated FTP login to LVGMC regardless of any
caller-supplied filename, and was only getting the traversal fix
(ValidateFileName) applied to it, not the auth-bypass fix. Traced every
caller of fetch.fetchFile/fetchWeatherStations in Server.scala/Main.scala
this time to confirm these are the only two HTTP-reachable call sites and
both are now gated.
