fix(i18n): add missing actionUsers/Monitoring/Analytics dashboard keys

Quick Actions rendered raw i18n keys instead of translated labels for the
Users/Monitoring/Analytics actions. Also reverts useMockData back to its
pre-session value (false) after manual local verification.

Adds docs/KNOWN-ISSUES.md to track bugs found during manual QA, deferred
for a batch fix after the sprint.

+1. **Quick Actions: 3 untranslated raw i18n keys.**
+   `dashboard.actionUsers`, `dashboard.actionMonitoring`,
+   `dashboard.actionAnalytics` rendered as literal key strings instead of
+   translated labels on the admin dashboard's Quick Actions section, because
+   `admin-dashboard.facade.ts` referenced them but they were never added to
+   `translations.ts`/`en.ts`/`ru.ts`/`hy.ts`.
+   - Found: 2026-07-15, manual browser verification of
+     `/:lang/backoffice/dashboard?devBypassAdmin=true`.
+   - Fixed: 2026-07-15, added the 3 keys to the interface + all 3 locales.
+
+## Notes (not bugs, just flag before shipping)
+
+- `src/environments/environment.ts`: `useMockData` was temporarily flipped to
+  `true` during this session's manual verification (so Categories/Products
+  dashboard cards showed mock counts instead of erroring against a
+  nonexistent local `/api/backoffice/*` backend), then reverted back to
+  `false` afterward - matches its pre-session value.
