Snapshot/preset capture is for framing a thumbnail, not editing, so it
should only move the camera:
- gate the selection manager, transform handles, floating menus, and the
tool manager (which renders the site boundary flags) behind
isCaptureMode, so clicking the scene no longer selects items or shows
editing controls
- hide zone meshes and the HTML zone tags while capturing
- force 3D on entry (the 2D/split floorplan panes render nothing useful
for a thumbnail) and restore the prior view mode on exit
