Update Enterprise comparison table

[enyst]

• I have read and reviewed the documentation changes to the best of my ability.
• If the change is significant, I have run the documentation site locally and confirmed it renders as expected.

Summary of changes

• remove the Enterprise-only row for centralized storage of agent conversations
• rename the multi-conversation row to "Multiple agent conversations in one place"
• mark that capability as available in both Local GUI and OpenHands Enterprise

This is a small docs-only table update, so I did not run the documentation site locally.

This PR was created by an AI assistant (OpenHands) on behalf of the user.

🟡 Acceptable - Simple table consolidation, but verify the claim is accurate.

KEY INSIGHT: You're asserting Local GUI now supports viewing multiple conversations in one place. Make sure this is actually true in the product, not just aspirational.

🟢 Good taste - Simple, pragmatic table consolidation that fixes an actual documentation inaccuracy. The verification was already provided in the thread (enyst confirmed Local GUI shows multiple conversations via RecentConversations component). No issues found.
