style(elixir): run mix format across the orchestration layer

Pre-flight for the new .github/workflows/elixir-ci.yml which runs
mix format --check-formatted. 61 files were unformatted; this catches
them up so the freshly-added CI workflow doesn't fail on first run.

Pure whitespace/style — no semantic changes.
