feat(phase-8-frontend): results loader UI + browsing list + 41 localization keys

* Pages/Results/ResultsList.razor — completed-events list with date range,
  sport/winner filter, search, footer count.
* Pages/Results/ResultsLoader.razor — driver page with two modes (load all
  in range / load selected events), live progress reporting via
  IProgress<PullResultsProgress>, summary line, cancellable.
* Replaces the Phase 5 Pages/Results.razor placeholder.

Service layer:
* IResultsBrowsingService + ResultsBrowsingService (Scoped, mirrors the
  Event/Anomaly browsing-service pattern). Reads IResultRepository +
  IEventRepository, projects to immutable view-model records.
* UiServicesExtensions: registers ResultsBrowsingService; also fixes an
  unrelated localization resolver bug (drop ResourcesPath since
  SharedResource lives in the Marathon.UI.Resources namespace already).

Localization:
* 41 new Results.* keys (RU+EN parity) covering both pages, filter chips,
  loader modes, progress states, and footer copy.

Tests:
* ResultsListTests + ResultsLoaderTests — 22 new bUnit tests covering
  filter narrowing, mode switching, progress aggregation, and empty
  states.
* FakeResultsBrowsingService support type for tests.
* MarathonTestContext registers the fake; TestData adds factories for
  EventResult/EventResultListItem.
