Add lastSeen and followerCount to topicSummaries across the indexer, DB, and client. The indexer now tracks the newest post seen time, updates follower counts idempotently on follow/unfollow, and preserves post metadata. The DB exposes lastSeen and followerCount from GET /topics and rebuilds both from the rooms store in the backfill. The client renders the four-column topics page with relative-time labels. By coder.
