Real LVGMC FTP credentials arrived today; real DMI HARMONIE credentials haven't. The combined flag would have enabled both the moment FTP's were ready, crash-looping the app on HARMONIE's still- placeholder values via parMapN — caught this before it happened (the Grib job was ~15 min from its first scheduled run). Split into ENABLE_LVGMC_FTP_JOBS and ENABLE_HARMONIE_JOBS so each provider can be enabled independently as its own credentials become real.
