[Bug]:Chat UI alignment issue on Windows: Messages are centered instead of split left-right

[cowleywang]

Bug Description

On the Windows Desktop version, the default theme does not correctly separate user queries and assistant responses into left and right bubbles. Instead, all text blocks are centered/stacked in the middle of the screen. This makes the conversation flow extremely cluttered and difficult to distinguish between what I asked and what the AI answered.

Environment

• OS: Windows 11
• App Version: Desktop v0.18.0
• Theme: all

Steps to Reproduce

1. Launch Hermes Agent Desktop on a Windows environment.
2. Select the default theme (or any built-in theme).
3. Send a message to the agent and receive a response.
4. Observe the layout of both the user's message and the agent's reply.

Expected Behavior

User messages should be right-aligned (or distinctively styled on the right side), and Agent responses should be left-aligned, matching standard chat bubble UX conventions.

Actual Behavior

Both the user's input and the agent's output are centered within the chat container, mixing up the content and rendering it unreadable.

Affected Component

Configuration (config.yaml, .env, hermes setup)
