Pro Plan: Cannot Add Over 5 Seats in Helicone

What's the problem?

On the Pro Plan, we should be able to add unlimited seats to a Helicone Organization. However, we can only add up to 5 seats, even with the Pro Plan subscription.

How to reproduce this?

1. Upgrade to the Pro Plan.
2. Try to invite more than 5 users to a Helicone organization.
