🐛 Fix workspace crash and cleanup viewport_ref event/resize handling (#10721)
Replace `globals/document` and `globals/window` with
`js/document` and `js/window` in workspace.cljs, removing
the unused `app.util.globals` import. This avoids "can't
access dead object" errors in Firefox when navigating between
pages/files, matching the existing pattern used in
viewport/hooks.cljs.

Fix a leaked MOUSELEAVE listener in viewport_ref.cljs — the
ref callback added a new listener on every mount but never
unregistered the previous one. Now uses standard
.addEventListener/.removeEventListener with a React ref to
track the handler for proper cleanup.

Fix ResizeObserver cleanup in viewport_ref.cljs —
`init-observer` is now a private function that only creates
an observer when a node is provided, and cleanup is handled
via the ref callback on unmount.
