KRACOEUS-7867: Fix errors in RegEx validation expressions

Fix errors in DD files for format validation:

1) validCharactersConstraint parent should be ValidCharactersConstraint and not JavaClassPatterConstraint;

2) Some validation patterns for Award Number had incorrectly specified 3 digits after the dash.
Wow. We use this pattern ALOT. A couple of options in my mind. All of these are for the awardNumber so they can probably all use a single parent bean definition. Or we can at least pull this pattern out into a definition using <util:constant/> and reference it using #{}.
