feat(virtual_table): Auto-reload when injected row leaves viewport

When an injected row has been committed (injected_committed=true)
and scrolling moves it out of the visible area:
- Sets needs_reload=true in result
- Clears injection state

This triggers the panel to refetch data from DB, where the
new row will appear in its proper sorted position.
