feat: add clickable source links to all report sections

YouTubeAudit: handle links to youtube.com/@{handle} with ExternalLink icon
InstagramAudit: handle links to instagram.com/{handle} with ExternalLink icon
ClinicSnapshot: domain is now clickable link, phone is tel: link
OtherChannels: Google Maps generates search URL, Naver Blog links to
  first blog post or search results (previously empty string)
transformReport: fills missing URL fields for Google Maps and Naver Blog
