On GitHub's hosted runners a job that isn't in a container can't reach a service by its name, so every database test failed with getaddrinfo EAI_AGAIN postgres. The check job now runs in node:24 (Gitea/Forgejo act_runner already runs jobs in containers) and installs ffmpeg so the sound and greeting tests run instead of skipping. The voicemail test's afterAll no longer throws when beforeAll failed. Checked locally by running the job's steps in node:24 next to a postgres:18-alpine reachable as "postgres": 481 passed, 5 skipped (ffmpeg). Task: M5-T3
