UI/UX issues

Epic to collect all UI/UX issues on the chat integration:

Starting with: https://github.com/liteflow-labs/marketplace-template/pull/31#issuecomment-1303154546

• [ ] Before typing a wallet address, the cursor is very small
• [ ] When creating a new chat an typing an address, if the address isn't found and the chat drawer is not opened, the error message appears below viewport and the back arrows moves down
• [ ] The border is a bit dark, maybe something like a lighter gray with a drop shadow would look better.

Another one, on full screen the demo app is not aligned, might be related to https://github.com/liteflow-labs/chat/pull/22

Also in "small mode", the topbar is changing height when starting a new chat
