# Objective

Fixes #59498 

Original issue mentioned problem with the alignment of text entered into
the agent editor compared with the thread title when in full expanded
mode. I was able to reproduce issue both in expanded mode and also when
resizing while not in expanded mode by dragging panel wide enough. After
more investigation, it seemed that all of the contents within the editor
(text entered, bottom row of elements) were not properly aligned on both
the left and right sides with other content in the agent panel.

## Solution

Moved horizontal padding to inner div that uses `max_content_width` in
`render_message_editor` so that it is calculated as expected as part of
the max width of the content.

- Dropped horizontal padding, keep vertical padding on outer `h_flex`
div. Changed `.p_2()` to `.py_2()` here .
- Added horizontal padding back to first child `v_flex` div that uses
`max_content_width`. Added `.px_2()` here.

After changes, elements within the editor are aligned on both the left
and right sides with the messages within the message history and the
contents of the title bar.

## Testing

I tested the fix on Linux visually, no tests were added due to the small
amount of changes and the strictly visual nature of the issue.

## Note

- A similar issue also seems to apply to the activity bar within
`render_activity_bar`, but it's less jarring, and this is also my first
PR, so I'm leaving it alone.
