Subject: [PATCH] Refactor: Use Gradle version catalog

This commit introduces the Gradle version catalog (`libs.versions.toml`) to manage dependencies and plugin versions centrally.

Key changes:
- Added `gradle/libs.versions.toml` defining versions, libraries, plugins, and bundles.
- Updated `app/build.gradle.kts` to reference dependencies and plugins from the version catalog.
- Updated project-level `build.gradle.kts` to use plugin aliases from the version catalog.
