Subject: [PATCH] refactor(editor): extract ai-chat label/feedback helpers to
 keep file under 800

The IconButton migration pushed ai_chat_panel.rs to 801 lines (over the
repo's 800-line cap). Move draw_label / chat_neutral_hover_color /
chat_neutral_feedback_color into the ai_chat_panel_controls sibling
(backend trait already in scope there) and re-export them, so callers
and tests are unchanged. ai_chat_panel.rs is now 780 lines.
