fix(compass-assistant): fix selecting text across messages

[lerouxb]

The previous hack for getting the docs to start at the bottom broke selecting text (for copy/paste) across messages. This fix still uses flex-direction: column-reverse to get them to stick to / start at the end, but it puts them all together in one div so that we don't have to reverse the order which breaks selecting text with the mouse across messages.

ie. It is now possible to select and copy a prompt plus the answer.

Pull Request Overview

This PR fixes a text selection issue in the compass-assistant chat component where users couldn't select text across multiple messages for copy/paste operations. The fix maintains the visual layout of messages starting at the bottom while enabling proper text selection by grouping all messages in a single container instead of reversing their order.

• Removes message order reversal that was breaking text selection
• Wraps all messages in a single div container to enable cross-message text selection
• Updates CSS selector to accommodate the new DOM structure
