fix(cli): BAT-022 slots 명령이 universe 대신 실제 슬롯 상태 표시 (dcy-016 후속)

`trex-core slots` 가 snapshot RPC 의 universe `assets`(portfolio)를 슬롯 상태로
오인 표시하던 갭 정정. snapshot envelope 이 슬롯 상태를 운반하지 않아 발생
(10개 슬롯인데 universe 1개·status 없음 — BAT-007 HTTP 슬롯 read 제거 후
슬롯 상태 read 표면 부재가 근인).

- REQ-028 (CHG-20260608-01): snapshot envelope 에 read-only per-slot `slots[]`
  additive 추가(AC-4). strategy `assets[]`(universe, no-price) 불변.
- REQ-032 (CHG-20260608-03): `_cmd_slots` 가 envelope `slots[]`(실제 슬롯 상태)
  표시 + `--status` 를 슬롯 status 기준 client-side 필터 + watchdog 결합.
  `universe` 는 `assets[]` 유지. `universe --json` 도 universe 데이터로 scope.
- canonical `portfolio.slot_to_dict` 단일화 — BAT-007 stub / BAT-008 envelope
  두 경로가 동일 슬롯 스키마(외부명 `entry_price` 유지, dcy-012 호환).
- interface-contract 에 `slots[]` 계약 + `assets[]` vs `slots[]` 구분 반영.

검증: 단위 338 passed + ruff clean + 신규 코드 데몬으로 실 PostgreSQL/RabbitMQ
운영 재현 PASS(slots=10·status·DB 일치·universe 분리·비침습). REQ-028/032
Implemented, BAT-022 release-candidate. pytest 인프라 게이트는 Human Approval
Memo 수용(운영 재현이 실 경로 커버).
