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.
Agree regarding parent bean definition. If you are going to do that anyway, please clean that regex up and probably use something like \d{5}-\d{5} or something
