feat(030): Dataset Lifecycle Workspace — Stats Bar, split-view, inline-edit, bulk actions

Backend:
- Add MetricItem, StatsCounts, ColumnDescriptionUpdate, MetricDescriptionUpdate DTOs
- Add metric_count to DatasetItem and DatasetDetailResponse
- Add server-side filtering via ?filter=unmapped|mapped|linked|all
- Add PUT endpoints for column/metric description inline-edit
- Add HTML stripping validation (max 2000 chars, plain text)
- Add WebSocket dataset.updated event on task completion
- RBAC: plugin:migration:WRITE for mutations, READ for reads
- 14 pytest tests (stats, filter, metrics, inline-edit, validation, 502/503)

Frontend:
- Rewrite +page.svelte as split-view orchestrator (387 lines)
- StatsBar.svelte — 4 metric tiles with aria-pressed, server-side filter dispatch
- DatasetList.svelte — card grid with progress bars, checkboxes, search
- DatasetPreview.svelte — presentational detail panel (container fetches)
- ColumnsTable.svelte — inline-edit with type chips, bold/italic fallback
- MetricsTable.svelte — inline-edit with expression hints
- 52 vitest tests across 7 test files
- i18n: 11 EN + 11 RU keys (with_mapping/с_маппингом)

Spec:
- 15 issues resolved (semantic label, filtering, endpoints, conflict, metric_count, RBAC, ID types, ports, i18n, validation, a11y, propagation, resize, perf, ownership)

Status: 14/14 backend tests pass, 52/52 frontend tests pass, build succeeds
Risk: Low — T051 browser validation pending (non-blocking)

## R3 — Backend: Stats Counts in GET /api/datasets
## R3 — Backend: Stats Counts + Server-Side Filtering in GET /api/datasets
**Decision:** `GET /api/datasets` response adds `stats` object with `total`, `unmapped_count`, `mapped_count`, `linked_count`. Computed by the existing `resource_service.get_datasets_with_status()` which already fetches ALL datasets before pagination. Stats are computed from the full (non-paginated) dataset list.
**Decision:** `GET /api/datasets` accepts optional query parameter `?filter=unmapped|mapped|linked|all`. When `filter` is present, the backend filters the full dataset list before pagination. Response always includes `stats` object with `total`, `unmapped_count`, `mapped_count`, `linked_count` computed from the full (non-paginated, non-filtered) dataset list.
**Rationale:** The Statistics Bar needs aggregate counts. Since the backend already fetches all datasets to compute `mapped_fields` enrichment, computing stats is O(n) over the already-loaded data — near-zero cost.
**Rationale:** Server-side filtering ensures that all matching datasets are returned, not just those on the current page. Stats represent global state independently of the active filter. Previously considered client-side filtering was incompatible with server-side pagination (a client can only filter the current page, causing mismatch between Stats Bar counts and visible cards).
**Alternatives Considered:**
- Separate `/api/datasets/stats` endpoint → rejected, adds unnecessary request

- **Accessibility (ARIA)**: Deferred to Polish phase. Components should use semantic HTML and `aria-busy`/`aria-live` where applicable.
- **Large-scale (200+ datasets)**: Client-side filtering works for 33 datasets. At 200+, Stats Bar counts remain server-computed; only list filtering would need server-side `?filter=` parameter. This is a future enhancement.

- Q: Stats Bar фильтрует клиентски или серверно? → A: Клиентская фильтрация по данным из API. Бэкенд в ответе `GET /api/datasets` возвращает 4 stats-числа (`total`, `unmapped_count`, `mapped_count`, `linked_count`). Клиенты фильтруют карточки без дополнительного запроса. Пагинация остаётся серверной. При фильтре пагинация переключает страницы отфильтрованного подмножества.
- Q: Stats Bar фильтрует клиентски или серверно? → A: Серверная фильтрация через query параметр. Бэкенд в ответе `GET /api/datasets` возвращает 4 stats-числа (`total`, `unmapped_count`, `mapped_count`, `linked_count`). При клике на метрику Stats Bar фронтенд отправляет запрос с `?filter=unmapped|mapped|linked|all` и `filter` сбрасывает `page` на 1. Пагинация остаётся серверной; бэкенд фильтрует полный список перед пагинацией. Stats-числа считаются глобально (не зависят от фильтра).
- Q: Каким запросом сохранять inline-edit описания колонок/метрик? → A: Два новых ss-tools эндпоинта: `PUT /api/datasets/{id}/columns/{col_id}/description` и `PUT /api/datasets/{id}/metrics/{metric_id}/description` (body: `{description: "text"}`). Бэкенд выполняет GET датасета из Superset, модифицирует одну колонку/метрику, PUT обратно полный объект. В Superset нет PATCH — только PUT с полным датасетом.
- Q: Как обрабатывать конфликт одновременного редактирования? → A: Last-write-wins. Бэкенд всегда выполняет GET→modify→PUT без проверки версии. Последний сохранивший перезаписывает. Для описаний колонок/метрик это приемлемый риск. ETag/блокировки — out of scope.
- Q: Параметр `override_columns` при PUT в Superset? → A: Всегда `override_columns=false`. Бэкенд получает полный датасет из GET, модифицирует только description нужной колонки, PUT обратно с `override_columns=false`. Superset сохраняет все колонки, не участвовавшие в payload.
