Allow non-admin users (user/viewer) to access / and /profile while
blocking admin-only pages. The dashboard layout now uses requireUser()
instead of requireAdmin(), and the sidebar filters nav items by role.
Non-admin users see a minimal welcome page without stat cards.
New test files (86 tests across 7 files):
- dashboard, users, groups, api-docs, portal, link-account specs
- role-access spec with full RBAC coverage for all 3 roles
