chore: cleanup — remove redirect shims, unused components, fix build artifacts

- Delete 8 redirect alias pages (approval-management, approvals, external-role-management,
  internal-role-management, help, role-modules, settings, workspace) that used onMount
  navigate — causes flicker and unnecessary AdminShell renders
- Delete unused Counter.tsx and Counter.css (test artifact, never imported)
- Update AdminSidebar to link directly to /admin/roles and /admin/runtime-roles
  now that redirect shims are gone
- Remove codex build hashes from page titles (Departments, Designations, Dashboard)
