Add ValidationException handling to middleware

Browse Source 
Enhanced the `ExceptionHandlingMiddleware` to handle
`ValidationException` from the `FluentValidation` library.
Set HTTP status code to 422 (Unprocessable Entity) for
validation errors and constructed error messages by
aggregating validation error details. Improved error
response clarity for validation-related issues.
