feat(monitoring): add DeepSeek monitoring end-to-end

- desktop: new DeepSeek page adapter and monitor registry
- desktop: extract generic AI auth helpers into shared module and
  skip binding when challenge signals are present
- admin-web: render DeepSeek HTML answers with inline citation anchors
  and surface reference-number badges on source cards
- server: fall back to inline_links/source_panel_links and read
  text/siteName fields when extracting DeepSeek citations
