Have the refresh button check for a new build too

Browse Source 
The version poller already diffs /api/version against the manifest
captured at boot -- hot-swapping changed CSS, reloading for changed
JS/HTML once playback allows -- but only on its own 60s tick or when the
tab regains visibility. Pressing refresh now runs that same check in the
background, so a tab left open across a deploy picks the new build up
when the user asks for fresh content rather than up to a minute later.
App.version.checkNow() exposes it; with no baseline (the endpoint was
down at boot) it just adopts the current manifest, since there is nothing
to compare against yet.

Verified against the running app: appending to style.css and pressing
refresh swapped the tag to style.css?v=<hash> with the page still alive,
and appending to a .js file reloaded the page.
