fix: credit display and top up and other UI display if personal membe… (#8784)

## Summary

Consolidate scattered role checks for credits, top-up, and subscribe
buttons into centralized workspace permissions (canTopUp,
canManageSubscription), ensuring "Add Credits" requires an active
subscription, subscribe buttons only appear when needed, and team
members see appropriately restricted billing UI.
