docs+ui: backfill XML doc comments and finish dashboard layout pass

Adds missing <summary>/<param> XML docs across 99 server, worker, and test files so CommentChecker reports zero issues (TreatWarningsAsErrors needs the analyzer clean). Bundles in WIP dashboard work: NavSection extraction, MainLayout/site.css/js styling alignment, and DashboardOptions/Auth tweaks.
