Server-020 incorrectly removed the duplicate `@page "/dashboard/X"` directive
from each dashboard Razor page on the assumption that `MapGroup("/dashboard")`
would prepend the prefix to Blazor SSR route matching. It does not — Blazor's
`@page` template matcher operates on the full URL path, not relative to a
MapGroup. The removal left the dashboard returning HTTP 500 with
"Unable to find the provided template '/dashboard/'" from
RouteTableFactory.CreateEntry on every page.
Restored the eight `@page "/dashboard/X"` directives. The accompanying
regression test still passes (it asserts the genuinely-double-prefixed shape
`/dashboard/dashboard/X` never appears — it never did, since the original
duplicates were `"/"` + `"/dashboard/"`, not `"/dashboard/"` repeated). XML
doc on the test rewritten to record what was actually wrong with Server-020.
Verified: gateway redeploy + `GET http://localhost:5130/dashboard` returns
HTTP 200 7.3 KB; `/dashboard/sessions` also 200.
