Improve DI, citation formatting, and search result output

- Inject IServiceScopeFactory in Documents.razor for better DI and async scope creation.
- Update citation formatting in Program.cs: sources now appear as a localized, numbered Markdown list with block quotes.
- Use a helper for consistent source/page formatting in TextSearchProviderOptions.
- Simplify RawRepresentation in VectorSearchService to just the page number.
