Refactor storage: remove Redis duplication, use proper data tiers

- Recipes: Now content-addressed only (cache + IPFS), removed Redis storage
- Runs: Completed runs stored in PostgreSQL, Redis only for task_id mapping
- Add list_runs_by_actor() to database.py for paginated run queries
- Add list_by_type() to cache_manager for filtering by node_type
- Fix upload endpoint to return size and filename fields
- Fix recipe run endpoint with proper DAG input binding
- Fix get_run_service() dependency to pass database module

Storage architecture:
- Redis: Ephemeral only (sessions, task mappings with TTL)
- PostgreSQL: Permanent records (completed runs, metadata)
- Cache: Content-addressed files (recipes, media, outputs)
