ScreenTinker ec450929ce Escape user-controlled data at the HTML sinks it actually reaches
A QA sweep found unescaped interpolations outside the SSO work. Auditing them properly
turned up 34 genuine HTML sinks; 23 carry data a user, a device or an identity provider
controls, and those are escaped here.

The ones that mattered:

  - app.js renders `user.name` in the shell on EVERY page, and an identity provider's
    `name` claim is stored verbatim, so an IdP could script the whole dashboard
  - designer element `label`/`location` and widget `location`/`query` land inside
    value="" attributes, where a single quote breaks out
  - content `folder` lands in a data-folder="" attribute
  - device `name` is set by the operator OR reported by the panel itself
  - workspace-members renders a SERVER error string through t(), which interpolates raw

⚠️ My first attempt was a codemod over everything my scanner flagged, and it was wrong.
It wrapped `progressText.textContent`, `block.title` and `confirm(...)` — none of which
are HTML, so escaping there shows users literal `<`. Worse, it wrapped
`title: ev.title ? ... : null`, an API PAYLOAD, which would have written escaped markup
into the database. I reverted the whole thing and narrowed to interpolations that are
genuinely inside an HTML template, then read all 34 and chose 23.

Skipped deliberately: static app strings, i18n output, ternaries yielding `selected`,
`window.location.origin`, and sites already escaped.

Verified in Chrome, not by inspection: the payload was seeded into user.name,
device.name, content.filename/folder, widget.name/config and video_wall.name (the first
attempt's seeds silently failed on column names — the API responses are checked now),
then eleven views were loaded. Zero executions, zero live img tags — AND the payload is
visible as inert text in 6/6 views, which is what proves the views rendered it rather
than the test proving nothing.

1609 tests; every frontend module parses as an ES module.
