v1.3.59 (Mar 11, 2026) Clearer Marketplace options on the free plan

The Marketplace now makes it clear what's available on your current plan.

What's changed:

- Themes and modules in the Marketplace are available on paid plans

- If you're on the free plan, you'll see an "Upgrade to Buy" button instead of the usual purchase option, so you know exactly what to do next

- Upgrading your plan unlocks Marketplace purchases right away
