chore: migration Groovy DSL + Java 25 via container Podman

- Remplace build.gradle.kts par build.gradle (Groovy DSL)
- Le Kotlin DSL est incompatible avec Java 25 (bug de parsing dans le compilateur Kotlin embarqué)
- Toolchain configuré sur Java 25, build exécuté dans eclipse-temurin:25-jdk
- Lombok 1.18.38 fixé explicitement (supporte Java 25)
