fix: restore MapFallbackToFile-only WASM configuration (c960860 style)

Reverted to c960860's proven configuration:
- NO MapRazorComponents (pure static WASM delivery)
- MapFallbackToFile for admin/portal SPA routing
- UseStaticFiles("/admin") for path-based static file serving

Issue with blazor.boot.json:
- MapRazorComponents should auto-generate it, but doesn't in our setup
- c960860 also had no MapRazorComponents, suggesting static-only approach works
- SRI integrity check failures may be browser cache or other cause

Current approach (c960860):
- WASM files served as pure static assets ✅
- MapFallbackToFile routes SPA requests ✅
- Next: Direct browser testing to verify WASM renders
