Bump Gradle image; add consumer ProGuard rules

Upgrade Gradle base image to gradle:9.0.0-jdk17 to align with AGP 9.x. Enable android.nonFinalResIds=true to support the AGP migration. Add placeholder consumer ProGuard rules for perpetual and referral feature modules. Update reproducible/base_image_tag.txt to reflect the new base image date.
