Functionality review:
- python-dateutil has been removed from the system requirements file
- I used grep to search for "From dateutils" and there were no instances of that, I also checked "import dateutils" and all dateutils were imported from submitty utillities and not sourced externally
- I pip removed python's date utils from my VM and the tests passed, and dates were completely fine on the webpage side (I was able to edit assignments as an instructor and change dates completely fine)

Hi @Farhanxikram! Thanks so much for approving the code! It looks like the CI workflows are currently paused and 'awaiting approval' to run. Could someone please trigger them when they have a second? I'll keep an eye on the results. |

Why is this Change Important & Necessary?
This PR removes the python-dateutil dependency. We already have a strong internal submitty_utils/dateutils parser, so using an external library for the same task is not necessary. Moving to a single parser simplifies the codebase and makes us less dependent on external tools.
Closes #11344
What is the New Behavior?
The functionality doesn't change for normal users. The backend has been changed to use the internal Submitty utilities for all date string parsing instead of the external dateutil library.
What steps should a reviewer take to reproduce or test the bug or new feature?
