Standard-conforming Format Descriptors with Fortran 2023

[okBrian]

Description

Fortran 2023 seems to strictly enforce standard-conforming format descriptors in format strings. Some of the print statements are missing commas between descriptors in format strings causing runtime errors when running gfortran (gcc 15) using the Fortran 2023 standard.

• Ran an example test case using gcc 15 locally.

Test Configuration:

• What computers and compilers did you use to test this:
  Locally, GCC 15.1.1

Checklist

• I ran ./mfc.sh format before committing my code
• New and existing tests pass locally with my changes, including with GPU capability enabled (both NVIDIA hardware with NVHPC compilers and AMD hardware with CRAY compilers) and disabled
• This PR does not introduce any repeated code (it follows the DRY principle)
• I cannot think of a way to condense this code and reduce any introduced additional line count

If your code changes any code source files (anything in src/simulation)

To make sure the code is performing as expected on GPU devices, I have:

• Checked that the code compiles using NVHPC compilers
