* feat(web): the Display tab is an ES-module page, with a page-visibility service (stage 4)
- core/visibility.js: each page gets ctx.visibility (whileVisible, every,
isVisible). Work registered there runs only while the page's tab is
active and the browser tab visible, and ends when the page is swapped
out. It reads the active tab from window.LEDVisibility, so it agrees
with the classic partials. The registry gained a mountContext option for
per-mount services.
- pages/display.js replaces display.html's two inline scripts. The 5 s
sync status poll runs through ctx.visibility.every; the status and
scroll-speed hint requests go through ctx.api with ctx.signal, as does
the Vegas order widget's plugin-list request. The Advanced toggle is a
delegated data-action; window.updateSyncUI is a deprecated alias.
- New DOM suites test_visibility_service.js and test_display_page.js;
test_display_partial_ids.js imports the module.

* refactor(web): no computed keys in the Display page's readout and destroy
Codacy's object-injection rule flagged v[id] and ctx.state[name].
