fix(firms): stop requesting the retired Suomi NPP source

Browse Source 
NASA stopped delivering Suomi NPP data on 2026-11-02 (FIRMS news page).
With a live MAP_KEY on 2026-11-04, VIIRS_SNPP_NRT came back ok with zero
rows while NOAA-20, NOAA-21 and MODIS returned 57k, 49k and 11k, so the
source only spent one transaction per refresh. The proxy now requests
NOAA-20, NOAA-21 and MODIS NRT. The "N" satellite label stays, so cached
or archived Suomi NPP rows still read SNPP.

Tests count sources from the list instead of assuming four, and a
regression test keeps the retired source out of the production list.

Refs #849
