📔 Objective

This PR updates the Protobuf Gradle Plugin to the latest version (v0.10.0). This was the last dependency blocking us from using the new Gradle 9 DSL, so that has been enabled as well.

Release Notes!

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR bumps the Protobuf Gradle Plugin from 0.9.6 to 0.10.0 in gradle/libs.versions.toml and removes the android.newDsl=false override in gradle.properties to adopt the new Gradle 9 DSL. The plugin was already approved and in use; the version bump is a minor update with release notes linked in the description. No remaining references to the removed newDsl flag exist, and the existing protobuf { ... } configuration in authenticator/build.gradle.kts remains compatible.
