Show message reactions

[gnprice]

This should include handling events that add and remove reactions.

From studying the web app's layout and the mobile app's current widget tree, I think the right place in that tree for a "reactions" row would be here (marked // <-- here):

Code

/// A Zulip message, showing the sender's name and avatar.
class MessageWithSender extends StatelessWidget {
  const MessageWithSender(
    {super.key, required this.message, required this.content});

  final Message message;
  final ZulipContent content;

  @override
  Widget build(BuildContext context) {
    final time = _kMessageTimestampFormat
      .format(DateTime.fromMillisecondsSinceEpoch(1000 * message.timestamp));

    return GestureDetector(
      behavior: HitTestBehavior.translucent,
      onLongPress: () => showMessageActionSheet(context: context, message: message),
      // TODO clean up this layout, by less precisely imitating web
      child: Padding(
        padding: const EdgeInsets.only(top: 2, bottom: 3, left: 8, right: 8),
        child: Row(crossAxisAlignment: CrossAxisAlignment.start, children: [
          Padding(
            padding: const EdgeInsets.fromLTRB(3, 6, 11, 0),
            child: Avatar(userId: message.senderId, size: 35, borderRadius: 4)),
          Expanded(
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.stretch,
              children: [
                const SizedBox(height: 3),
                Text(message.senderFullName, // TODO get from user data
                  style: const TextStyle(fontWeight: FontWeight.bold)),
                const SizedBox(height: 4),
                MessageContent(message: message, content: content),
                // <-- here
              ])),
          Container(
            width: 80,
            padding: const EdgeInsets.only(top: 4, right: 2),
            alignment: Alignment.topRight,
            child: Text(time, style: _kMessageTimestampStyle)),
        ])));
  }
}

Greg, are you aware of any problems with putting it there, or conflicts with your work on #174 / #175?

Sounds good to me!

There won't be any substantive conflict with my branch for #174 / #175. Might be a small textual conflict from touching nearby lines of code, but it'll be easy to resolve.
