Describe the bug

The chat box in the AgriTech Assistant page has display issues in both modes:

1. In dark mode:

• The chat input area remains white instead of adapting to dark mode.
• Typed text is duplicated, making it hard to read.

2. In white mode:

• The chat box styling looks inconsistent and not visually appealing.

To Reproduce

1. Go To Home Page
2. Click On Chat Button
3. Open the AgriTech Assistant page.
4. Enable dark mode and start typing in the chat box.
5. Observe the white background and duplicated text.
6. Switch to white mode and check the chat box appearance

Expected behavior

• The chat box should adapt properly to both dark and light modes.
• Typed text should appear once and be readable.
• The design should look clean and user-friendly in both modes.

Additional context

This affects usability, readability, and the overall user experience.
