fix(patches): streamer mode dialog list anonymization

- drop streamer-mode-online: keep real last-seen text per user pref
- add streamer-mode-forum-topic: anonymize ForumTopic::chatListName
  (per-topic seed = channel id ^ rootId so distinct pseudonyms)
- extend streamer-mode-name: public PeerData::noteNameUpdated bumps
  _nameVersion so Entry::_chatListNameText cache rebuilds on toggle
- ag_refresh: walk histories + topics, invalidate chat-list-entry
  message-view cache (HistoryItem::invalidateChatListEntry resets
  MessageView _textCachedFor so sender prefix re-renders)
- streamer-mode-avatar/style: hunk-header line drift only from
  noteNameUpdated insertion above
