fix(entity)!: validate value after applying transform

[MohitKS5]

Issue

• Validate type function is called before transform function. It allows user to do anything in transform including return invalid values.
• Transform receives abridged value not the one supplied by user due to alterations by validateType

Fix

Validate value type after transform. Also fixes #299 and similar issues.

Transform is supposed to receive (value, data) as arguments where value is supplied value not after type conversions like string to number. ValidateType function does this and various similar conversions for flexibility.
