feat(#37): compact message tile - decouple time, cell_tower heard, inline @mentions

- Clock setting (System / 12h / 24h) in App Settings; chat times follow it + locale.
- Channel tile: always-on metadata row - time + hops on inbound, time + cell_tower
  heard count + status on outbound - decoupled from the message-tracing toggle. The
  via-path stays behind tracing.
- Drop the auto reply-to block and the most-recent-sender guess; @mentions now
  render inline in the message text.
- Direct chat: same clock-aware time formatting.

Closes #37
