feat(ui): render every application template except the loading screen as a Vue view

The scene chrome, cockpit, Display controls, command dock, layer panels,
Context rail, welcome card and Provider Settings move verbatim into
src/ui/views and mount into their hosts before the page is translated and
wired. Each view renders the same elements, attributes and text as its
template; Vue keeps whitespace between elements as one space, and no view
markup sits under a white-space: pre rule.

Template asset URLs stay literal, view files are left out of Prettier so
the markup is not reflowed, and the Node component loader moves to build/
and is exported as build/register-vue for host test runners. Hosts that do
not initialize Core's locale pass localePicker: false instead of editing
the markup.
