feat(bat-052): WAC 실현손익 리포트 통합 (REQ-109/110/111, dcy-035)

- portfolio.py: RealizedPnlItem/RealizedPnlResult 데이터클래스 추가; PortfolioHubReadPort에 get_realized_pnl 포트 메서드 추가 - hub_read.py: GET /v1/portfolios/{id}/pnl/realized 어댑터 구현 (from/to/symbol query, 비2xx/네트워크→PortfolioHubUnavailableError) - stub_read.py: get_realized_pnl 고정 결과 stub 추가 (무네트워크) - operator_report.py: OperatorReport에 WAC 4필드+degrade 2필드 추가; apply_wac_to_report/buy_fee_by_asset 헬퍼; render_text/render_json WAC 섹션 - cli.py: _cmd_report에 WAC 경로(portfolio-hub 설정 시) + degrade 경로 통합 (REQ-111: base_url 미설정/Unavailable → 식별가능 에러, 폴백 없음) - tests: 51개 신규 테스트 (domain sweep, hub_read, stub_read, operator_report, cli_report_wac); 전체 717 passed, 47 skipped Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VHtM5Ws1HKCKQ4JGi6GRb5
