Adds /admin-users CRUD on the ops backend, covering listing, plan/role/KOL
toggles, subscription expiry, status flips and password resets, with a
configurable default plan code. The ops console exposes a new top-level
"用户管理" view and reorganises the sidebar so 操作员管理 and 审计日志
move under a "系统设置" group; AccountsView is renamed accordingly.

Vue 3 + Ant Design Vue SPA scaffold for the internal ops console. Ships
the auth, account list, and audit log views that consume the new ops-api
endpoints, plus the nginx/vite/typecheck plumbing.
