Refactor buildSrc and update dependencies

This commit refactors the `buildSrc` module by:
- Removing the `setupLibraryDefaults()` extension function from `ProjectConfig.kt` as its functionality is largely covered by standard Gradle plugin configurations.
- Inlining version numbers for Moshi and various testing libraries directly into `Dependencies.kt`, removing them from `Versions.kt`. This simplifies version management for these specific libraries.
- Removing unused version declarations from `Versions.kt`.

Additionally, this commit updates the following dependencies:
- Kotlin from 2.1.21 to 2.2.10
- Android Gradle Plugin from 8.11.0 to 8.12.2
- KSP from 2.1.21-2.0.1 to 2.2.10-2.0.2
- Dagger from 2.56.2 to 2.57.1
- AndroidX Navigation from 2.8.9 to 2.9.3

The `targetSdk` was also removed from the `app-common` module's `defaultConfig` as it's typically inherited or set at the app level.
