Этап 1: version catalog (libs.versions.toml) — устранён дрейф версий

- gradle/libs.versions.toml: единый источник версий (Gradle 9.3 авто-подхват).
- 15 module build.gradle мигрированы на libs.* (скриптом, регекс по group:name).
- Устранён дрейф: coroutines 1.8.1/1.10.1→1.10.1, coil 2.6.0/2.7.0→2.7.0,
  lifecycle 2.8.1/2.8.7→2.8.7, activity-compose 1.9.0/1.10.1→1.10.1,
  core-ktx 1.13.1/1.15.0→1.15.0. Firebase в core/push → bom (был explicit 24.0.1).
- Compose BOM в каталоге вместо дубля в каждом модуле.
