Subject: [PATCH] feat(adminui): add DriverTypePicker landing page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds /clusters/{ClusterId}/drivers/new picker page (Task 3.1). Renders
a 9-card Bootstrap grid — one card per driver type — each linking to
/clusters/{ClusterId}/drivers/new/{slug}. No data fetch; type list is
hardcoded. Route collides with DriverEdit.razor's same directive; Task
3.3 removes the duplicate to resolve the runtime ambiguity.

+@* TODO(3.3): This route collides with DriverEdit.razor's @page "/clusters/{ClusterId}/drivers/new".
+   Task 3.3 removes the /drivers/new directive from DriverEdit.razor so this page takes over.
+   Blazor resolves route conflicts at runtime, not compile time, so the build succeeds now. *@
