💡 [FEATURE] - Add support for error placement customization

[isonnymichael]

Summary

Allow customization of where the error message is placed — before or after the input element — through the options config.

Basic Example

validateForm('my-form', {
  errorPlacement: 'before' // or 'after' (default)
});

• Option errorPlacement accepted in config
• Errors appear in the correct DOM position
• Default behavior remains after
• Works in all browsers without layout issues
