Closes#12803
### What problem does this PR solve?
The chat input textarea in the Chat UI (and Embed UI) has a fixed height
and cannot be resized, causing poor UX when users type messages longer
than 2 sentences. The input becomes cramped and difficult to read/edit.
**Root cause:** The `Textarea` component in
[NextMessageInput](cci:1://file:///ragflow/web/src/components/message-input/next.tsx:62:0-290:1)
had `resize-none` and `field-sizing-content` CSS classes that prevented
resizing, and the existing `autoSize` prop was not being utilized.
**Solution:**
- Removed `resize-none` and `field-sizing-content` classes
- Added `autoSize={{ minRows: 1, maxRows: 8 }}` to enable auto-expand
- Added `max-h-40` class to limit maximum height to 160px
The textarea now auto-expands from 1 to 8 rows as users type longer
messages.
