Bug description

When a declarative settings form contains a checkbox field with storage_type: internal, saving the value triggers a fatal TypeError:

OC\AppConfig::setValueString(): Argument #3 ($value) must be of type string, int given,
called in /var/www/html/lib/private/Settings/DeclarativeManager.php on line 343

Root cause: DeclarativeManager::saveInternalValue() unconditionally calls AppConfig::setValueString() regardless of the field type. A checkbox field sends 0 or 1 (integer) from the frontend, but setValueString() enforces a strict string type, which raises a TypeError.

Steps to reproduce

1. Create a declarative settings form in an app with a checkbox field, storage_type: internal, section_type: admin:

[
	'id' => 'checkbox_form',
	'priority' => 1,
	'section_type' => DeclarativeSettingsTypes::SECTION_TYPE_ADMIN,
	'section_id' => Application::APP_ID,
	'storage_type' => DeclarativeSettingsTypes::STORAGE_TYPE_INTERNAL,
	'title' => 'Enable feature',
	'fields' => [
		[
			'id' => 'my_checkbox',
			'title' => 'My checkbox',
			'type' => DeclarativeSettingsTypes::CHECKBOX,
			'label' => 'Enable',
			'default' => false,
		],
	],
]

2. Open the admin settings page where the form is registered.
3. Click the checkbox to toggle its value.
4. Observe a 500 Internal Server Error on POST /ocs/v2.php/settings/api/declarative/value.

Expected behavior

The checkbox value (true/false or 1/0) should be saved without error. The DeclarativeManager should cast the value appropriately (e.g. call setValueBool() for CHECKBOX) or at minimum cast to (string) before calling setValueString().
