Namespace incorrectly shows paid plan status and upgrade options for future-dated subscription

Summary

A namespace is incorrectly displaying as being on a paid plan when the subscription has a future start date. Additionally, the system is showing upgrade options for a subscription that hasn't started yet.

Steps to Reproduce

1. Navigate to a namespace that has a future-dated paid subscription (Premium)
2. Check the namespace's subscription status in the UI
3. Observe the billing page shows the option to Upgrade to Ultimate

⚠️ To check if the system treats the namespace as if it currently has active paid features.
