fix!: use authority admin, remove params

ref: liftedinit/manifest-ledger#21

The way the SDK handles authorities is so difficult to have many admins and is going to be very confusing for people.

Maybe we only let 1 entity be the admin (set blank keeper up to load params, setup everything else, then finish keeper setup). This way every authority can be the p.Admin param from the POAKeeper

Idea 2

• Just remove / ignore admins in the params store, weod not need
• Only use authority for any logic. IsAdmin is just the k.authority
• Fix e2e
• Fix simulator

A single x/group account covers the multiple administrators use case.

You can even set the x/group policy to be the sole admin of the group, i.e., the group is the admin of itself.

This is what we do on Manifest.

I'll go the 2nd approach way with just using the standard authority as the admin. The complexity to support an array is far too much and not worth it relative to just using groups or DAOs.

Also, we could just entirely delete params to remove the graceful exit logic. hmm

Then will move optional POA admin override into the POA module itself for testing vs being done app side. nicer UX

Sim failures due to hardcoded authority account now (instead of from params)
