DARK exposure 20211205/00112406/desi-00112406.fits.fz is under NIGHT 20211205 but has header NIGHT=20211204. Unluckily, it was also a 300s dark, which appears to have taken the spot as the first 300 sec DARK of the night even though the header keyword mismatch prevented it from getting used (initially no dark*.slurm job was created; I submitted the "correct" dark 112463 by hand).

Various remediations to be more robust:

• only use DARK if PROGRAM starts with "CALIB Dark" (from the zeros+dark sequence) instead of "DARK" from the 90min dark sequences.
• if an exposure is rejected, don't let it take the spot for the nightly badcolumn dark
