Favicon badge: removed crossOrigin='anonymous' from _drawFaviconBadge Image
lazy-init. Same-origin favicons don't need CORS credentials; setting it caused
silent cache-miss failures when the browser had the asset cached without CORS
headers, preventing the canvas from drawing.
Page title: new updatePageTitle() centralizes title logic. Format:
'(N) hostname - muxplex' when N sessions have unseen bells, otherwise
'hostname - muxplex'. Hostname uses device_name setting with fallback
to location.hostname. Called from pollSessions on every tick, from
loadServerSettings callback, and immediately when device_name input changes
(updating _serverSettings.device_name in place first so the helper sees the
latest value without waiting for the debounced PATCH).
Replaced 3 scattered document.title assignments with updatePageTitle().
Updated 3 existing source-pattern tests to reflect the new centralised
approach; added 2 new tests for updatePageTitle existence and pollSessions
call site.
