feat: migrer vers Symfony 8, PHP 8.4 et les dépendances majeures associées

- PHP 8.3 → 8.4 (Dockerfile + composer.json)
- Symfony 7.0 → 8.0 (tous les composants symfony/*)
- API Platform 3.x → 4.x : migration openapiContext → openapi: new Operation(...)
- Doctrine DBAL 3 → 4 : suppression use_savepoints, replace prepare/executeQuery
- Doctrine ORM 2.x → 3.x : ClassMetadataInfo → ClassMetadata, setParameters → setParameter
- Doctrine Bundle 2.x → 3.x, Fixtures Bundle 3.x → 4.x
- zenstruck/foundry 1.x → 2.x : ModelFactory → PersistentObjectFactory, getDefaults → defaults
- phpmd/phpmd 2.x → 3.x-dev (seule version supportant Symfony 8)
- phparkitect 0.3 → 0.8 : NotDependsOnTheseNamespaces prend un array
- symfony/mercure-bundle 0.3 → 0.4, symfony/monolog-bundle 3 → 4
- Suppression de runtime/frankenphp-symfony (intégré nativement dans symfony/runtime 8)
- worker.Caddyfile : suppression de APP_RUNTIME (détection automatique Symfony 8)
- Routes errors.xml/wdt.xml/profiler.xml → .php (Symfony 8 supprime le XML)
- Types::ARRAY → Types::JSON dans Entity/Manga.php (DBAL 4 retire array type)
- Suppression de src/Schedule.php (doublon vide avec MonitoringSchedule)
- Tests : hydra:Collection → Collection, hydra:member → member (API Platform 4)
