SmartUp Developer 4c71148ff9 feat: one-click upstream auth refresh from custom page viewer
- Add linked_upstream_id to CustomPage model with DB migration
- New POST /api/custom-pages/{pid}/refresh-auth endpoint extracts
  credentials from active remote browser and updates linked upstream
- PageViewer toolbar shows key icon button when page has linked upstream
- CustomPages form adds upstream dropdown for remote_browser pages
- Auth capture extracts New-Api-User from localStorage uid/user/self API
- Upstream client sends New-Api-User header in cookie auth mode
- Fix auth capture dialog: transparent background, field persistence,
  login URL defaults to base_url/login, focus on click for keyboard input
- Fix upstream test ASCII encoding with non-header characters validation
