feat(monitoring): match citations by canonical link and scope summary by brand/keyword/platform/date

Replace the domain+title fuzzy alias scoring with a canonical
candidate-key index built from published-link aliases — only exact
matches now resolve to a SaaS source, eliminating false positives
across articles sharing a host (e.g. m.163.com vs www.163.com).

Surface the summary scoping that already existed on loadCitationRanking
/ loadCitedArticles by accepting brand_id, keyword_id, ai_platform_id
and business_date on CitationSummary, plumbing them through the handler
and admin tracking view.
