Two bugs: (1) populateConvTtsBackends() referenced window._ttsBackends
which doesn't exist — fixed to use module-scope _ttsBackends directly.
(2) Broken hook that wrapped window.refreshTtsBackendAvailability (never
set on window) — replaced with _ttsRefreshHooks array dispatched at end
of refreshTtsBackendAvailability().

- New light UI: fixed 220px sidebar, single scrolling page, 8 named sections
- Static files split by concern: style.css, app.js, loader.js, nav.js
- Each page section is its own partial in static/sections/s-*.html
- loader.js fetches all section partials in parallel, then loads app.js and nav.js
- All original functionality, element IDs, and API endpoints preserved
