Add GitHub-style activity contribution graph

Record create/update/delete events across novel content (chapters, beats, characters, arc stages, tags, locations, questions) into an append-only ActivityEvent log, aggregate by UTC day, and surface as a heatmap on the novels list and each novel's dashboard. Backfills history from existing CreatedAt timestamps on first boot after the migration.
