The LazyColumn was using reverseLayout=false when TalkBack was active to work
around a Compose accessibility traversal bug. This placed new messages at the
top of the screen, distorting the reading order for TalkBack users.
With Compose BOM 2026.06.00, reverseLayout=true now works correctly with
TalkBack traversal, so remove both workarounds:
- Always use reverseLayout=true in TimelineView
- Remove the .reversed() for expanded groups in TimelineItemGroupedEventsRow
Note: this change should be manually tested with TalkBack to verify correct
traversal order (oldest messages first, newest last).
