Timeline UX: reverse sort, search, right-justified timestamps

- r key reverses chronological order (newest/oldest first) with
  breadcrumb indicator
- / key opens search in timeline view
- Timestamps right-justified on the header line (sender left, time right)
- ListConversationMessages now respects TextFilter.SortDirection
- Updated footer keybindings to show new keys
