ifcviewer-web: stop the log overlay from covering + blocking the canvas

Browse Source 
The status overlay was position:fixed top/left/right with max-height
80vh and pointer-events:auto — a near-fullscreen div that both hid the
model and swallowed mouse events, so orbit drags over most of the canvas
did nothing. Move it to a small bottom-left box, set pointer-events:none
so it never intercepts navigation, and collapse it to a few dimmed lines
once the app goes live (errors re-expand it). It still auto-scrolls to
the newest line.
