When dark mode is enabled, it is applied only to the left sidebar section. The rest of the chat interface (chat area, header, input box, and background) remains in light mode, causing inconsistent UI and poor user experience.

Environment:
Platform: Web
URL: dev.akindervolunteer.com
Module: Chat
Browser: Chrome

Steps to Reproduce:

1. Open the application
2. Navigate to Chat section
3. Enable or trigger dark mode (or land in dark-themed state)
4. Observe UI

Expected Result:
Dark mode should be applied consistently across the entire interface, including:

• Sidebar
• Chat header
• Chat messages area
• Input field
• Background

Actual Result:
Only the left sidebar is rendered in dark mode
Remaining UI stays in light mode
