Fix weather sat 0dB SNR: increase sample rate to 2.4 MHz for Meteor LRPT

Browse Source 
The default 1 MHz sample rate was too low for SatDump's meteor_m2-x_lrpt
pipeline, causing NOSYNC and 0.000dB SNR. Bumped to 2.4 MHz (SatDump
recommendation) and wired up the WEATHER_SAT_SAMPLE_RATE config value
so it actually gets passed to decoder.start() from both the auto-scheduler
and manual start route.
