Chris Troutner 92ce290873 Refactor topic recency indexing: cut CRAP, harden property coverage ...

- Extract roomFromEntry/applyPost from backfill collectSummaries so its
  cyclomatic complexity drops from 7 to 4 (CRAP 7.0 -> 4.0), and extract
  the shared roomRange key bounds from getTopicPostTxids/listRoomFollowers.
- Add indexer property tests over arbitrary post/follow/unfollow
  interleavings: postCount conservation, newest-height recency shape,
  replay idempotence, and inverted-key ordering.
- Add DB property tests for the topic index backfill: conservation,
  recency shape, stale-record removal, and inverted-key ordering.
- Cover the topic action error paths (invalid push counts, oversized
  topic message), the topic-query room fallbacks, and the client
  openTopic/topicFeedPath navigation.
