Migrate to Gradle version catalog

Centralize dependency and plugin version management using Gradle's version catalog feature.
This improves maintainability by having a single source of truth for all versions.

Changes:
- Add gradle/libs.versions.toml with all dependency and plugin versions
- Update all build.gradle.kts files to use version catalog references
- Configure version catalog in all settings.gradle.kts files
- Replace hardcoded versions with catalog references throughout the project
