feat(02-02): frontend auth store, router guard, Login/Register views

- frontend/src/stores/auth.js: useAuthStore with accessToken in memory
  only (never browser storage); login() accepts options.backupCode
- frontend/src/api/client.js: extended with Bearer token injection,
  401 auto-refresh retry, all auth/admin API functions, changePassword
- frontend/src/router/index.js: auth routes added (/login, /register,
  /password-reset, /account, /admin); beforeEach guard redirects
  unauthenticated users to /login with redirect param
- frontend/src/layouts/AuthLayout.vue: centered bare layout for auth pages
- frontend/src/views/auth/LoginView.vue: three-step flow (password, TOTP,
  backup code); "Use a backup code instead" link; UI-SPEC copywriting
- frontend/src/views/auth/RegisterView.vue: registration with
  PasswordStrengthBar; HIBP error display; UI-SPEC copywriting
- frontend/src/components/auth/PasswordStrengthBar.vue: 4-segment bar
- frontend/src/components/ui/AppSpinner.vue: animate-spin SVG spinner
- Stub views: PasswordResetView, NewPasswordView, AccountView, AdminView
- .gitignore: exclude frontend/node_modules, dist, package-lock.json

npm run build exits 0. All acceptance criteria verified.
