Subject: [PATCH] feat(virtual_table): Implement Ctrl+N local injection handler

- Ctrl+N creates injected row below current selection
- Uses startInjection() to initialize injection state
- Automatically starts editing first column
- Updates selection to show injected row as selected
- Adjusts visible row count when injection is active

No longer emits insert_row_requested - injection is handled
internally by the widget.
