🤖 fix: display queued messages inline with other messages (#649)

_Generated with `mux`_

Fixes queued messages appearing as a separate floating element instead
of inline with the rest of the message flow.

## Changes
- Moved QueuedMessage component inside the scrollable message container
- Positioned after streaming barrier for consistent flow
- No functional changes, purely visual improvement

## Before
Queued message appeared below the scrollable area as a separate element

## After  
Queued message appears inline with other messages in the chat flow
