refactor(adminui): retire generic DriverEdit.razor

All 9 driver types now have typed pages; DriverEditRouter dispatches
to them directly. Unknown DriverType strings (e.g. legacy rows) render
an explicit error notice instead of falling through to a generic
editor — the failure mode is now visible, not silent.
