StreamMessageMetadataStyle class

Defines the appearance of metadata rows including username, timestamp, edited indicator, status icon, and spacing. All properties use StreamMessageLayoutProperty for placement-aware resolution. Use StreamMessageMetadataStyle.from for uniform values across all placements.

    return isEnd ? Colors.blue : Colors.grey;
  }),
)
