Align console UI with school-iot-admin and wire login to serverschool

UI / layout
- rebuild left mode: full-width blue header (60px) + white sidebar below + card-style tags view
- introduce design tokens in variables.css (brand #347df9, sidebar 240px, menu item 49px)
  and theme overrides for dark / dark-blue themes
- restyle navigation bar (logo + platform name / top nav / tools + user), logo, sidebar
  (selected state: light blue bg + blue bar + bold), tags view, app main
- global styles: .app-container white card, .head-title, .btn-blue/.btn-white,
  el-table / el-dialog look, brand color injected into --el-color-primary
- add favorites store (localStorage) wired to sidebar star and header top nav
- disable template watermark / footer / promo notifications by default

Login (serverschool)
- port school-iot-admin login page (background art, right side card, keep-login)
- OAuth2 password mode: GET /oauth/token (raw axios) + GET /uc/account/current
- port phone lookup (/wx/getAccoutList) and forget-password flow
  (/sms/sendCode + /sms/verifyCode) as components/login/Forget.vue
- user store exposes accountInfo / accountType / teamId / roleId and strips password

Infra
- move all devServer proxies and env vars from school-iot-admin/vue.config.js
  (default targets point to production)
- fix empty sidebar: guard short-circuit skipped setRoutes when login page already
  fetched user info
