feat: REQ-002/REQ-010 implementation — assets.tag_ids column + GET /v1/assets admin catalog (BAT-012)

- REQ-002 scope redefinition: portfolios.tag_ids → assets.tag_ids UUID[] column with GIN index
- REQ-010 augmentation: GET /v1/assets redesigned as admin catalog endpoint (admin-only, no token_type branching)
- Asset tagging infrastructure: tag_ids column, archived flag synthesis for inactive tags, list_assets N+1 optimization
- DB migration 20260521_0023: assets.tag_ids UUID[] NOT NULL DEFAULT '{}', idx_assets_tag_ids_gin
- Test suite: 17 new test cases for assets.tag_ids + GET /v1/assets AC-9~12 (362 tests total)
- Documentation: runtime flows, release baseline, batch verification all updated
- BAT-012 added to REL-001 Included Batch and marked release-candidate

 ## Recent Change Log Summary
 
+- 2026-05-21: REQ-002 / REQ-010 Approved → Implemented (CHG-20260521-03 각각) — BAT-012 confirm-batch-verification 완료. 362 PASSED (32 신규: REQ-002 AC-1~4 8건 + REQ-010 AC-9~12 9건 + AC-1~8 회귀 9건 + 단위 6건). assets.tag_ids 마이그레이션·도메인·repository·schema·GET 라우트 archived 합성 모두 evidence 확보. REQ-010 BAT-002 trace는 superseded by BAT-012로 표기.
+- 2026-05-21: REQ-002 Implemented → Approved (CHG-20260521-02) — 파일명(`req-002_assets-tag-ids-column.md`)·dcy-002 FR-2와 본문 정합성 회복. 기존 본문(portfolios.tag_ids)은 dcy-001 분리 이전 portfolios==asset 시절 흔적으로 REQ-003과 중복이었음. 새 범위(assets.tag_ids + `idx_assets_tag_ids_gin`)는 미구현 — BAT-003 verification은 REQ-002 범위 무효화. REQ-009 Impacted Area에 cross-reference 추가(CHG-20260521-02, Implemented 유지). 신규 batch 편입 필요.
 - 2026-05-21: REQ-010 Implemented → Approved (CHG-20260521-02) — REL-001 smoke 검증에서 GET /v1/assets가 dcy-001 시점 portfolio 조회 코드를 유지 중인 불일치 확인. dcy-003 옵션 B(REQ-013 Deprecation) 후속의 GET admin catalog 재정의를 본 REQ에 augmentation. AC-9~12 신설, app/api/v1_assets.py GET 라우트 재정의 + AssetCatalogListResponse 추가. BAT-002 verification 재실행 필요.
 - 2026-05-21: REQ-001~018 (17건, REQ-013 제외) Approved → Implemented — BAT-001~006 confirm-req-implemented 일괄 전환. BAT-001(REQ-009/011/014), BAT-002(REQ-010/012/015), BAT-003(REQ-001/002/003/006), BAT-004(REQ-004/005), BAT-005(REQ-007/008), BAT-006(REQ-016/017/018). DB-integration ACs는 REL-001 배포 시 최종 확인 예정.
 - 2026-05-21: REQ-030/031/032 Approved → Implemented — BAT-010 confirm-batch-verification 완료. 330/330 PASSED (32 신규 tests in test_v1_portfolios_tags_comments.py). GET /v1/portfolios/{id}/tags 신설; POST/DELETE tag disabled 409 + service/client 403 보강; comment CRUD 4종 신설; baseline 4종 갱신(interface-contract/runtime-flows/data-model/project-structure).
