fix(tui): use takeLast(3) for events, add bridge/TUI tests for snapshot recentEvents

- Change EventHistoryStrip take(3) to takeLast(3) so it shows the 3 most
  recent events instead of the 3 oldest (chronological order is oldest-first)
- Add bridge test confirming replaySnapshot populates recentEvents from the
  event store (with 3 different event types mapped correctly)
- Add TUI SessionsReducer test confirming processSessionSnapshotMessage maps
  EventEntryDto entries from the snapshot into TuiEventEntry on the summary
