Better error handling for dates, added submitted filter criteria

[wes-otf]

Fixes #4548. This handles an invalid date the same as invalid/non-existent query params rather than erroring out. In the long term, it would be better to indicate to the user that something wasn't right with their query though or no results were brought. When an invalid query is entered, it'll show the no results prompt!

I also added the submitted drop down filter, as staff have been using that a bit recently

Test Steps

• Ensure putting an incorrectly formatted date in the query bar doesn't result in a 500 error
  • ie. submitted:>=205-04-01 submitted:<=2025-04-30
• Ensure applications can be filtered by submitted date using the new drop down

As we move away from jQuery it might be nice to check out a vanilla JS datepicker like https://air-datepicker.com too

Edit: this was already mentioned in #4475

Works well in my testing. Nice new submitted filter.
