feat(uxp-panel): fix hover tooltips + add compact list view toggle

Tooltips: the floating .tip-bubble used position:fixed, which UXP's
engine does not render reliably, so tooltips never appeared. Switch to
position:absolute (body never scrolls, so viewport coords still map),
add scroll-offset compensation, and guard against UXP returning 0 for
window.innerWidth/innerHeight.

List view: add a toolbar toggle (grid vs compact list). List view shows
a small 50x28 thumbnail with name/meta and an inline status chip per
row, fitting many more clips on screen. Defaults to list, persists via
localStorage when the host allows it.
