fix: add @rendermode InteractiveWebAssembly to all admin pages

Problem: Page components were not rendering content because @rendermode was only
on App.razor and Routes.razor, not on individual @page components.

Solution: Add @rendermode InteractiveWebAssembly to all admin page components
to ensure they render interactively in WebAssembly context.

Result: All admin pages now render their content correctly.
