Fix Blazor WASM loading, add missing filter panel bind parameters, and gate nav behind auth

Remove UseBlazorFrameworkFiles() that blocked MapStaticAssets() from serving fingerprinted
Blazor framework files. Add Operators/ProfitCenters/WorkCenters alias parameters to their
respective filter panels so @bind-* two-way binding works in SearchEdit. Move all nav links
inside AuthorizeView so they only show when logged in.
