CPQ improvements

We've shipped several enhancements to make complex quotes clearer and easier to manage, with more control over their published state.

What's New:

• Contract total panel: A new panel shows your contract value breakdown when you're configuring pricing
• Custom phase names: Add descriptive names to contract phases (like "3-Month Trial" or "Year 1 Enterprise") that appear on your published quotes
• New quote view mode: Group pricing by either contract phase or product on published quotes to match your customers' preferred view
• Quote unpublishing: Now you can unpublish quotes when you need to make changes or prevent customer access.
