In the trade chat screen, the bottom input bar overlaps the last messages in the conversation. The message list does not have sufficient bottom padding to account for the input bar height, causing content to be hidden behind it.

Steps to reproduce:

1. Open a trade chat with multiple messages
2. Scroll to the bottom of the conversation
3. The last message(s) are partially or fully hidden behind the input bar
4. No additional scroll space available to reveal the obscured content

All messages should be fully visible above the input bar.
