Document scheduler split and METEO_* removal

+- [x] Deleted the dead `METEO_*` fetch path (`fetch/csv/FetchService.scala`,
+      its empty test, and its env vars everywhere). Confirmed via git history
+      it wasn't a separate vendor: the first commit (2023-04-13) included
+      real sample CSVs from it with a Latvian header identical to the
+      LVGMC/open-data fields — the same underlying LVĢMC data, just an
+      earlier delivery mechanism superseded by the FTP feed and never
+      cleaned up. It was never wired into anything that runs.
+- [x] Split scheduled jobs so the working open-data fetch (and cleanup) can
+      run without the FTP/Harmonie jobs' placeholder credentials
+      crash-looping the whole app: `ENABLE_SCHEDULED_JOBS` now only gates
+      the safe jobs; a new `ENABLE_LEGACY_PROVIDER_JOBS` (default false)
+      independently gates the FTP station fetch and Harmonie fetch. Turned
+      the former on for Rocky staging; real station data now accumulates
+      automatically every 30 minutes with no manual trigger needed.
+- [ ] FTP (`fetch/lvgmc/FetchService.scala`) and Harmonie/DMI credentials are
+      the user's own follow-up (asking the original dev about the FTP
+      partner feed; registering for free DMI Open Data). Both stay gated
+      behind `ENABLE_LEGACY_PROVIDER_JOBS`/missing keys — not removed — so
+      no code changes are needed once real credentials arrive, just setting
+      them and flipping the flag. Worth confirming DMI's endpoint migration
+      away from `dmigw.govcloud.dk` before wiring anything.
 - [ ] Investigate open real sources for water temperature (Ūdens) and the
       LVĢMC forecast CSV workspace, following the same open-data-portal
       approach used for station observations.
