fix: change all admin pages to prerender: true for WASM bootstrap

All Page components now use:
@rendermode @(new InteractiveWebAssemblyRenderMode(prerender: true))

Attempted solution based on observation that Login.razor (prerender: true)
works correctly while Dashboard.razor (prerender: false) fails WASM init.

Result: blazor.boot.json still not generated, WASM bootstrap still fails.

Indicates deeper SDK issue with ASP.NET Core 10 Preview Blazor WASM
initialization mechanism, not fixable by render mode configuration alone.

Changed files:
- All 30+ admin Page components: prerender: false → true
- Program.cs: MapRazorComponents added (required for WASM)

Status: WASM bootstrap blocked at fundamental SDK level.
