fix: update CI workflow for correct branch and Gradle setup

- Add master branch to push triggers (repo uses master, not main)
- Specify Gradle 8.12.1 in setup-gradle action
- Remove gradlew chmod step (no longer needed)
- Use direct gradle commands instead of ./gradlew wrapper

These changes ensure the CI pipeline triggers on the correct branch
and uses a consistent Gradle version via the setup-gradle action
rather than relying on the wrapper script.
