Add e2e route crawl coverage for admin and common pages

Crawls every admin route plus the common routes shared by all roles, asserting no console errors or failed responses along the way, and checks role-based menu visibility and 401 access control for admin-only routes.

File: `e2e/crawl/route-crawl.spec.ts`. Verified: 7 passed (5 tests + 2 cleanup).

JIRA Issue: FR-3295

Start with e2e/crawl/route-crawl.spec.ts and review the existing route crawl coverage and its verified 5 tests plus 2 cleanup checks. Confirm that every admin and common route is crawled without console errors or failed responses, role-based menu visibility is checked, and admin-only routes reject unauthenticated access with 401.
