Small improvement on Warpcast mobile: least interacted with

If you go to your profile and tap following, we now show you a list of users you haven't replied to or reacted to. And you're able to unfollow all with two taps.

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

Useful as we prepare to migrate follows to Hubs. 

To start, each Farcaster user (i.e. an FID) can follow up to 2500 other users. We'll likely have a way to increase this amount once we're on mainnet later this year.

Right now, there are only ~90 users following >2500 users, and this feature should solve for 80/90.

This is definitely going to need to change as the protocol grows. One of my least favorite things about Twitter was the hard limit of 5k following without an adequate follower ratio.

There's only 1400 active casters rn. No wonder only 100 follow more than 2500.

Without first class list support this is unfortunate.
