[2.1.x] UI Patterns UI

Hi Christian. Good work on this !
I have an issue installing this module.
Looks like something is missing in entity type configuration, which do config_translation module complain.

[10-Mar-2025 09:14:07 UTC] PHP Fatal error:  Uncaught Error: Call to a member function getPath() on null in /var/www/html/web/core/modules/config_translation/src/ConfigNamesMapper.php:247
Stack trace:
#0 /var/www/html/web/core/modules/config_translation/src/Routing/RouteSubscriber.php(39): Drupal\config_translation\ConfigNamesMapper->getOverviewRoute()
#1 /var/www/html/web/core/lib/Drupal/Core/Routing/RouteSubscriberBase.php(37): Drupal\config_translation\Routing\RouteSubscriber->alterRoutes(Object(Symfony\Component\Routing\RouteCollection))
#2 [internal function]: Drupal\Core\Routing\RouteSubscriberBase->onAlterRoutes(Object(Drupal\Core\Routing\RouteBuildEvent), 'routing.route_a...', Object(Drupal\Component\EventDispatcher\ContainerAwareEventDispatcher))

Adding definition of edit_form in routing file fixes it

entity.sdc_component_form_display.edit_form:
  path: '/admin/structure/component/{sdc_component_id}/form-display/{form_mode_name}/edit'
  defaults:
    _entity_form: 'sdc_component_form_display.edit'
    _title: 'Edit a component display'
  requirements:
    _permission: 'administer sdc_component_form_display'

@Christian, i think you miss my comment #6

Thanks @Christian, i miss that.

MR has to be rebased

Weight of fields is different between configuration and display.

In configuration :

In display :

in addition to the work done today, i did the following changes :

 -  getSdcComponentId => getComponentId 
 - ComponentController::load => components are now sorted by provider and label 

 - BUGFIX in ComponentController,
    -  'component_form_display.' . $component->getPluginId() . '.add_form'; => 'entity.component_form_display.' . $component->getPluginId() . '.add_form';
 - Improve UiPComponentFormDisplayForm::buildForm
    - any source settings form not deriving from SourcePluginPropValue, was proposing widgets without titles.. i implemented a method to properly set a title in the other cases.
 - in ComponentFormDisplay, removed two functions not part of the interface and unused 
    - removed : public function getSdcComponentId():string {
    - removed : public function getSdcComponentDefinition():array {
 - renamed the hook "ui_patterns_component_prepare_view" to an alter hook "ui_patterns_component_pre_build" =>  hook_ui_patterns_component_pre_build_alter
 - add cache management to ui_patterns_ui_ui_patterns_component_pre_build_alter
