Topic list rows have inconsistent metadata and aggressive truncation

[cassi-volkova]

Environment

Android app 1.0.5 (versionCode 14) from commit d03af65, tested on a physical Pixel 5 running Android 14.

Reproduction

1. Open a channel that contains several topics with recent messages.
2. Compare adjacent topic rows and long topic names.

Actual result

Some rows contain only a title while others include sender, time, and preview. Long names are truncated early, the channel identity is reduced to a narrow avatar rail, and unread counts can visually replace the channel avatar or initial.

Expected result

Topic rows use a consistent hierarchy for title, sender, time, preview, and a separate unread badge, following the approved mobile design.

Impact

Scanning and distinguishing topics is slower, and unread state is visually ambiguous.
