[feature] New Section "STATUS PAGES", grids of just the xpath output

Some idea for STATUS PAGES, so you can abritrarily build a list of interesting status to watch, and there can be multiple status pages

The issue does not identify any files, tests, or entry points. First clarify the status-page data model, page configuration, XPath output format, and UI behavior for multiple pages; define acceptance criteria for creating, displaying, and updating a grid before implementation begins.
