Problem

UrlConfigurator always sets the default_protocol form option. Only UrlType (and the types whose parent is UrlType) defines it, so a UrlField rendered with another form type fails when the form is built:

// keep the clickable URL on index/detail pages but use a plain text input in forms
UrlField::new('website')->setFormType(TextType::class);
// UndefinedOptionsException: The option "default_protocol" does not exist.

Fix

Before setting the option, the configurator asks the form registry whether the field's form type defines default_protocol (FormRegistryInterface::getType($type)->getOptionsResolver()->isDefined(...)). So:

• UrlType behaves as before
• types extending UrlType through getParent() keep receiving the option
• other types (e.g. TextType) no longer get it

UrlConfigurator gets form.registry as a constructor argument in config/services.php.

Tests

tests/Unit/Field/UrlFieldTest.php:

• testDefaultProtocolOptionIsNotSetWhenFormTypeDoesNotDefineIt() (TextType)
• testDefaultProtocolOptionIsSetWhenFormTypeExtendsUrlType() (a test type whose parent is UrlType)
• the existing default_protocol tests still pass with UrlType

Results:

• make tests ARGS="tests/Unit/Field/UrlFieldTest.php": OK (52 tests)
• make tests ARGS="tests/Unit/Field tests/Functional/Fields": OK
• make tests-parallel: OK (3688 tests)
• phpstan and php-cs-fixer: no errors
