feat(messaging): Add double-tap to react with 👍

[jamesarich]

This commit introduces a new quick-reaction feature, allowing users to send a "👍" reaction by double-tapping a message.

• Added an onDoubleClick handler to MessageItem.
• Implemented the double-tap gesture in MessageListPaged to trigger onSendReaction when not in selection mode.
