Remove the dead METEO_* fetch path

Confirmed via git history it's not a separate vendor: the very first
commit (2023-04-13) included real sample CSVs from it with a Latvian
header identical to the LVGMC/open-data fields — same underlying LVĢMC
data, just an earlier delivery mechanism superseded by the FTP feed and
never removed. Never wired into anything that runs (Server.scala's
import was already commented out).
