Remove Java JaCoCo badge auto-update pipeline

[Copilot]

This PR removes Java JaCoCo badge maintenance from CI. The Java SDK workflow still runs tests and publishes test summaries, but no longer generates badge SVGs or opens badge-update PRs.

• Workflow cleanup (.github/workflows/java-sdk-tests.yml)

  • Removed the JaCoCo badge generation step.
  • Removed the auto-PR step that committed badge updates from main.

• Repository cleanup

  • Deleted unused badge generator script: .github/scripts/generate-java-coverage-badge.sh.
  • Deleted generated badge assets:
    • .github/badges/jacoco-generated.svg
    • .github/badges/jacoco-handwritten.svg

• Net effect

  • Java CI remains focused on build/test/reporting.
  • Coverage badge artifact churn and automated badge PR noise are eliminated.
