[CoR] Approval card text is improperly wrapped in default Chat layout

OS: Win11 x64
Build Version: 0.12.8-alpha.0
VS Code Insiders Version: 1.137.0-insiders

Repro Steps:

1. Create a project using Azure Project with a project description: a to-do list web app with a REST API and a database.
2. Generate a project plan.
3. Wait for an approval request to appear in the chat panel.
4. Observe the approval card displayed in the default Chat layout.

Expect:
The approval message should be displayed in a readable format. Text should wrap naturally and remain readable without requiring users to resize the Chat panel.

Actual:
The approval card renders the prompt with excessive word breaking. The approval request becomes difficult to read and understand until the Chat panel is manually widened.

More Info:

1. Reproduced during Project Plan generation.
2. The issue occurs in the default Chat layout.
3. Expanding the Chat panel immediately restores correct rendering.
4. Appears to be a layout or text-wrapping issue specific to approval cards rather than the approval content itself.

Reproduce the issue by generating a project plan and viewing the approval request in the default Chat layout, then compare it with a widened Chat panel. Trace the approval card rendering entry point and verify that its text wraps naturally and remains readable without resizing the panel.
