ci: add workflow_dispatch + dry_run support to release workflow

[umaucher]

What

Adds workflow_dispatch trigger with a dry_run flag to the release workflow, and restructures it into two jobs.

Why

Before creating a real release tag it must be possible to validate the full build/test/coverage pipeline without side effects. Previously the workflow only triggered on release: created, making it impossible to test without creating an actual GitHub release.

Changes

• workflow_dispatch trigger with version (X.Y.Z) and dry_run (default: true) inputs
• prepare-release job (skipped on dry run): bumps MODULE.bazel, commits, creates tag + GitHub release
• release-verification job: runs build → unit tests → Rust coverage → C++ coverage → uploads ZIP artifact; attaches to release only when not a dry run
• Fixes setup-bazel @0.15.0 → @0.18.0 (canonical version in cicd-workflows)
• Fixes upload-artifact @v4 → @v6 (canonical version in cicd-workflows)
• Keeps existing release: created trigger for backward compatibility

Testing

Dry run can be triggered from this branch without merging:

gh workflow run release.yml --repo eclipse-score/persistency --ref um_release_workflow --field version=0.3.3 --field dry_run=true
