Complete Umami event tracking coverage across all partials

Add data-umami-event attributes to all meaningful links that were
missing tracking:
- Footer: try-it, GitHub, docs, API, blog, newsletter, community,
  about, contact, and all social icons (Framagit, GitHub, feedback,
  Mastodon, email)
- CTA join section: primary signup button
- Usage footer: survey, Matrix, IRC, and about links (with per-page
  content base name for granular tracking)
