Subject: [PATCH] feat(virtual_table): Add injection state for Ctrl+N between
 rows

State fields:
- injected_row_idx: visual index of injected row
- injected_row_id: ID after commit (NEW_ROW_ID until saved)
- injected_committed: true when saved to DB

Result fields:
- injection_committed: panel should INSERT
- injection_row_idx: where it was injected
- needs_reload: table should refetch from DB

Helper methods:
- hasInjection(), startInjection(), clearInjection()
- markInjectionCommitted(), isInjectionVisible()
