chore(gui): lazy-render collapsed panels to reduce watcher count (#10772)

Browse Source 
Adds a `lazyCollapse` directive that renders panel body content only
while expanded. Collapsed panels contribute zero watchers — content is
added to the DOM on expand (`show.bs.collapse`) and removed after the
collapse animation completes (`hidden.bs.collapse`).
