fix: resolve CI failures from navigation refactoring

TypeScript fixes:
- Add 'as const' to icon type in useAlertRulesNav.test.tsx for proper type narrowing
- Remove unused imports in NotificationPoliciesPage.test.tsx and ContactPoints.test.tsx
- Remove unused import in triage/Triage.tsx
- Restore missing useURLSearchParams import in ContactPoints.tsx
- Restore ActiveTab enum export (used by template pages for URL generation)

Go lint fixes:
- Move nolint:staticcheck comment to line directly before flagged usage in navtree.go

i18n:
- Run yarn i18n-extract to update translation files

All tests passing:
- Backend navtree tests: ✅
- TypeScript compilation: ✅
