Add agile estimates to action cards

We know you've been waiting for this one! As of today, we've added the ability to include agile estimates in Fibonacci format on all action cards.

This functionality will act as an App in Hive, so to enable it, you'll need to visit your Hive App section and turn it on. Once Agile has been enabled, you'll see an App section in each action card where you can assign the action points.

Thank you to Daniela from PHD for requesting this feature!
