Improvements to pricing plan management

^{Major Upgrade}

Marketplace Managers can no longer delete pricing plans or individual plan items that are currently linked to Active, Pending, or Suspended subscriptions. However, they can hide the required plans. This ensures billing stability and prevents subscription errors.

📝 Note: The hide option is only available for editions that have more than one price plan.

With this update:

The system now checks for linked subscriptions before allowing a deletion. If you attempt to delete a plan in use, a warning dialog appears explaining that the plan is linked to a subscription. The UI suggests Hiding the plan as an alternative.
Partners can now hide pricing plans from the storefront and administrative views without deleting the underlying data. This is ideal for "sunsetting" old plans while maintaining support for existing customers.
Hidden plans are completely removed from the public storefront and are not selectable for new opportunities by Agents or Marketplace Managers.
Existing Subscriptions and Renewals: Subscriptions currently on a hidden plan will continue to renew on that plan automatically (subject to your auto-renew settings).
- If a customer on a hidden plan enters the "Update" flow, their current hidden plan remains visible so they can see what they are currently paying for. However, once they switch to a different plan, the hidden plan will no longer be available to them.
To ensure your marketplace always has a checkout option, you cannot hide the last remaining active pricing plan. In this scenario, the Hide pricing plan checkbox will be disabled.
