New pages under /ops/admin: Summary dashboard, Users (list + edit +
recharge + create), LLM provider keys management, Billing ledger and
usage records.
Shared AuthContext (lib/auth.tsx) fetches /auth/status once and
supplies user/role to RequireOps, RequireAdmin, and OpsLayout.
OpsLayout shows a ⚙ 超管 nav link for admins. RequireOps now grants
admin users access without an extra ops-role probe.
