[DanIredell-NOAA]

At next upgrade, please improve the ncoda_qc job adding dcom input files checking with WARNING message when they are not available for the following ush scripts and dcom input data files -

• ush/rtofs_ncoda_ssh_qc.sh - wgrdbul/adt/rads_adt_ncoda_*.nc
• ush/rtofs_ncoda_vel_qc.sh - wgrdbul/ndbc/YYYYMMDDHHhfr.nc

You can reference the IT test ncoda_qc jobs log files on DOGWOOD -

• /lfs/h1/ops/test/output/20240718/rtofs_global_ncoda_qc.o158420203
• /lfs/h1/ops/test/output/20240718/rtofs_global_ncoda_qc.o158427777

Modified ush/rtofs_ncoda_ssh_qc.sh to check if any rad_adt_ncoda_*.nc files exist before proceeding.
Modifed ush/rtofs_ncoda_vel_qc.sh to check if hfr netcdf files exist before proceeding.

If either above do not exist, then output warning message.
