Add relative date functionality to Date fields

Add relative date functionality to Date fields

In the Report Date, Start Date, or End Date field, let me write a natural language relative dates, such as "7 days ago". This is quite critical if y'all actually want us to use Bovi-Insight Modern (BIM).

In this example, I entered "7 days ago", but unlike the other report systems, the date fields don't remember "7 days ago" and BIM simply enters the absolute date.
