BIM viewer auto-recovers after switching to the scan tab and back
Switching from the BIM tab to the Scan tab and back sometimes left the BIM viewer in an error state, requiring a manual retry click before the model would reload.
The viewer now detects when it becomes visible again after a context loss and restarts itself automatically. No error dialog appears, and no manual action is needed — the model reloads on its own. If context is lost while the BIM tab is still in the foreground (uncommon), the manual Try Again option still appears as a fallback.
A separate issue with the version selector has also been corrected. When switching from one location to another, the version toggle could display a version from the previous location rather than the one actually rendering. The selector now always reflects the active version, regardless of navigation history.
