fix(auth): make logout POST+CSRF and propagate session loss to other tabs
- Switch /logout from GET to POST with CSRFMiddleware so it matches the
  SPA's existing HttpUtil.post('/logout') call (previously 404'd silently)
  and blocks GET-based logout via image tags or link prefetchers. Handler
  now returns JSON; the SPA already navigates client-side.
- Return 401 (instead of 404) from /panel/api/* when the caller is a
  browser XHR (X-Requested-With: XMLHttpRequest) so the axios interceptor
  redirects to the login page on logout-in-another-tab, cookie expiry,
  and server restart. Anonymous callers still get 404 to keep endpoints
  hidden from casual scanners.
- One-shot the 401 redirect in axios-init.js and hang the rejected
  promise so queued polls don't stack reloads or surface error toasts
  while the browser is navigating away.
- Add the CSP nonce to the runtime-injected <script> in dist.go so the
  panel loads under the existing script-src 'nonce-...' policy.
- Update api-docs endpoints.js: GET /logout doc entry was missing.
