fix: Simplify signing config to avoid getByName error in CI

- Remove explicit debug signing config modification
- Let Android Gradle Plugin handle debug signing automatically
- Only create 'release' signing config when keystore exists
- Prevents 'Unknown signing config debug' error in GitHub Actions
- Debug builds work without keystore (auto-signed by AGP)
