fix: reduce CI noise from apt-get, sdkmanager, stunnel, and Gradle (#140)

- Add -qq to apt-get update/install in Dagger toolchain to suppress
  verbose package-list output (hundreds of lines on cold cache)
- Wrap sdkmanager in silent-on-success pattern — only shows output
  on failure, like the build_runner and flutter pub get steps
- Set debug = warning in stunnel config to suppress LOG5 (info/notice)
  startup lines while keeping LOG4 (warning) and above
- Add org.gradle.welcome=never to android/gradle.properties to
  suppress the "Welcome to Gradle N.NN!" banner
- Filter SKIPPED Gradle tasks, Gradle Daemon startup messages, and
  gcloud support-page promo lines in run_firebase_test.sh

Errors and warnings are preserved in all cases.
