feat(activity-log): phase 6 - dashboard widget + settings panel + docs

- Dashboard 'Recent Activity' widget: latest 5 entries, live prepend, 'View all' -> Activity tab
- Settings 'Activity Log' panel: retention (enabled/max_days/max_entries) GET/PUT, clear (confirm + auth-required toast), CSV/JSON export
- audit-log vs ephemeral debug Log Viewer distinction note + cross-links
- public helpers fetchRecentEntries/renderCompactEntry on activity-log.ts (reused, no dup markup)
- README Activity Log section; i18n across en/ru/zh
- review fixes: clear 401 surfaces toast; empty widget transitions on first live event

+### Activity Log
+
+The **Activity** tab is a persistent, queryable audit log of everything LedGrab has done — entity changes, auth events, device connections, and system actions.
+
+- Filter by category (auth, device, entity, capture, system), severity, actor, entity type, date range, or free text
+- Live-append of new events as they happen
+- Export as CSV or JSON (authentication required)
+- Entity crosslinks navigate directly to the relevant card
+- **Retention settings** (Settings → Activity Log): configure max age, max entry count, and toggle recording on/off
+- **Clear log** (Settings → Activity Log, requires authentication) — audited: a system entry records who cleared the log and when
+
+> **Note:** The Activity Log is distinct from the **debug Log Viewer** (Settings → General → Open Log Viewer). The Log Viewer is an ephemeral real-time tail of the server's Python log stream (WARNING/ERROR lines, resets on disconnect). The Activity Log is a structured, persistent SQLite-backed record of semantic application events.

 ## Handoff to Next Phase
 
-<!-- Final phase. Note anything for the final review / documentation writer. -->
+This is the **final implementation phase**. All six phases are complete. Notes for the final reviewer:
+
+**What was implemented in Phase 6:**
+
+- `features/dashboard.ts`: `_loadRecentActivityWidget()`, `_renderRecentActivityList()`, `_startRecentActivityLive()` — SSE live-update listener (`server:activity_logged`) with cap-to-5 prepend logic. Widget appended after `getOrderedSections()` loop (outside the layout toggle system — always visible). Non-blocking: `.catch()` on the async load call.
+- `features/settings.ts`: `loadActivityLogSettings()`, `saveActivityLogSettings()`, `activityLogSettingsExport(format)`, `clearActivityLog()` — all exported and exposed on `window` via `app.ts` + `global.d.ts`.
+- `templates/modals/settings.html`: Activity Log rail entry (System group, cyan channel) + full panel (`id="settings-panel-activity_log"`) with enabled toggle, `max_days`/`max_entries` inputs, Save, CSV/JSON export, Clear (danger zone). Audit-vs-debug distinction note with cross-links in both directions (`closeSettingsModal(); openLogOverlay()` and `closeSettingsModal(); switchTab('activity_log')`).
+- `static/css/activity-log.css`: `.dal-*` dashboard widget styles + `.ds-info-note` / `.ds-inline-link` settings panel utilities appended (no new CSS file).
+- `static/locales/{en,ru,zh}.json`: 32 new keys each under `dashboard.section.recent_activity`, `dashboard.recent_activity.*`, `settings.tab.activity_log`, `settings.activity_log.*`.
+- `README.md`: "### Activity Log" section documenting tab, retention settings, export, and audit-vs-debug distinction.
+
+**Reused Phase 5 helpers (no duplication):**
+
+- `fetchRecentEntries(limit)` and `renderCompactEntry(entry)` — new public exports added to `activity-log.ts` in Phase 6 (not duplicated in dashboard.ts).
+- All `.al-*` CSS classes from Phase 5 are reused in the compact rows inside the widget.
+
+**Build verification:** `tsc --noEmit` clean, `npm run build` passed (2.8 MB bundle, 258 ms) at time of implementation.
+
+**Remaining manual smoke test (requires server restart):**
+
+- Dashboard widget loads recent entries, prepends live on new activity, "View all →" switches to Activity tab.
+- Settings panel reads/writes retention, Save shows toast, Clear prompts confirm then deletes, Export downloads authed blob.
+- Cross-links: note in Settings opens Log Viewer overlay; note in Log Viewer links back to Activity tab.
+
+**Outstanding open note from PLAN.md:** The manual browser smoke test across the whole feature (P5 note) remains open — it requires a server restart to exercise the live API endpoints. Recommend as first step in the final review session.
