Allow non-admin users to access dashboard

- Change dashboard route from adminGet to authed middleware
- Show account counts and audit events only for admin users
- Show welcome message for non-admin authenticated users

Security: non-admin users cannot access account lists or audit
events; admin-only data is gated by claims.HasRole("admin") in
the handler, not just at the route level.
