The HTML branch of openFilePreview(), the Page pill and the fall-through
to the source view on a refused mint had no test. The jsdom harness from
file-preview-markdown.test.ts now drives them with a stubbed fetch:
- a successful mint renders an iframe at the minted URL whose sandbox
has allow-scripts and never allow-same-origin, with the pill pressed;
- a refused mint shows the source view with its Edit button and hides
the pill;
- the pill flips page and source and persists
codeman:filePreviewHtmlRendered, and with the pref off the preview
opens as source without a mint request.

What counts as an HTML page lived in three places: HTML_VIEW_EXTENSIONS
on the server, a /\.html?$/ regex in the terminal link provider and a
HTML_PAGE_EXTS set in panels-ui.js. The two frontend copies are now one
rendersAsPage() next to previewsInFileViewer() in constants.js, used by
the link provider (and through it every grid tile and the split's Pane
B, which share registerFilePathLinkProvider) and by openFilePreview()
and its toolbar. A new test pins it equal to the server's list.
toggleFilePreviewPage() now returns the preview load, so a caller (and
the coming frontend test) can await the flip.
