refactor: JobEngine cleanup + crypto compose refactor + sprint plans + timeline merge prep

- Remove zombie JobEngine WebService (no container runs it)
- Remove dangling STELLAOPS_JOBENGINE_URL, replace with RELEASE_ORCHESTRATOR_URL
- Update Timeline audit paths to release-orchestrator
- Extract smremote to docker-compose.crypto-provider.smremote.yml
- Rename crypto compose files for consistent naming
- Add crypto provider health probe API (CP-001) + tenant preferences (CP-002)
- Create sprint plans: crypto picker, VulnExplorer merge, scheduler plugins
- Timeline merge prep: ingestion worker relocated to infrastructure lib
